The Personal Logo inserter is part of Hauppauge Capture and can be found in the Settings tab. It only runs with the HD PVR 2 (all models) and Colossus 2. There is also a standalone version which is installed with the HD PVR 2 Installer.

Some tips on using the Personal Logo application

• The logo must be less than 1200pixels x 550pixels and be a GIF, BMP or PNG format. PNG files are recommended since they can be transparent. When creating a PNG file, create 24-bit transparent logos.
• In Hauppauge Capture, click the Settings tab and then click 'Enable Personal Logo'. Then click 'Browse' and find your logo. Once you open the logo, you can position it on the screen by dragging it around with your mouse. Then click the 'Apply' button to add your logo.
• If you change the record resolution, the HD PVR 2 record application will calculate where to reposition it to keep it in the same spot.
• You can adjust the transparency by using the Alpha slide bar. All the way to the right makes the logo fully opaque, while moving it to the middle makes the logo semi-transparent.
• The settings are 'sticky'. Once set, they will be applied to all future recordings (unless you re-run the Personal logo program and make changes).
• Here is a short test video we made using the logo inserted by the Personal Logo application. https://www.youtube.com/watch?v=0T1phlzaz28

Hauppauge Capture System Requirements

I was wondering how I can record my commentary with game audio?

With the Hauppauge Capture application, you can plug your microphone into the 'mic input' on your PC. Hauppauge Capture will mix your game play audio with microphone audio. With Hauppauge Capture, there are seperate volume adjustments for game play and microphone audio. You can also add PC sound (music or Skype audio) to mix together PC audio with game audio and your game commentary.

In some cases, in order to have third party chat in your recordings and streams, you might need the Hauppauge Chat cable.

What types of video sources can I record?

Hauppauge Capture supports HDMI, Component, S-Video and composite video sources. Audio can be from HDMI, SPDIF (on Hauppauge recorders with optical audio connectors) or left/right audio.

Computer Sound Cards

Does Hauppauge Capture support HDCP?

No.

If you have a video source with HDMI out and the HDMI is protected with HDCP, this video cannot be recorded.

On game consoles, you can turn off HDCP so that your game play can be recorded (you can find instructions to do this with the Xbox One and PS4 on the Hauppauge support page).

With cable or satellite boxes, if your HDMI video is protected with HDCP, you can use Component video. Component video is HD and can always be recorded.

I am getting squeaky audio when I record game commentary with my microphone. How can I fix this?

Sometimes the audio sampling rate of the microphone is not matched to the audio recording. In order to match them up, set the sampling rate of the microphone to 48Khz. Here's how to do this:

• On your PC, go to the speaker icon on the right side of your desktop's toolbar, right-click the speaker icon and select 'Recording devices'.
• Then in the new window that opens, locate your microphone and the right-click it in the list and select the option 'Properties'. A new window called 'Microphone Properties' will open.
• Go to the 'Advanced' tab. There you'll see a section named 'Default Format', click the drop down menu and select this from the list: 2 channel, 16 bit, 48000 Hz (DVD Quality). Then click apply, restart your PC and give the recording another try.

Can I record composite video or S-Video?

Yes. In Hauppauge Capture, set the Video Source to Composite or S-Video.

Recordings from composite or S-Video are still made in the H.264 format.

To use S-Video with some Hauppauge recorders, you will need to use the optional Hauppauge AV cable model 6021252 which you purchase on the Hauppauge Webstore.

I'm trying to record from a Nintendo Switch, but I'm getting a 'No HDMI signal detected' message. How can I fix this?

The basic problem is that the Nintnedo Switches' HDMI resolution, in 'Atomatic' mode, is not what the HD PVR 2 needs to sync up.

Do this:

• In the Switch settings System settings > TV output > TV resolution, change from 'Automatic' to either 720p or 1080p
• you must connect the power to the docking station before connecting the HDMI lead to the HD PVR 2

I'm not getting audio on my TV monitor, but I have audio in my recordings. How can I fix this?

Some users have reported that they get audio in their recordings, but do not hear audio on their monitor. We find that this is caused by the Hauppauge HD PVR 2 being able to accept AC-3 audio but the monitor is only two channel audio.

In Hauppauge Capture, go to the Advanced Settings -> Audio Encode and click the button which says 'Disable HDMI AC3 support'. This forces your video source to output 2 channel audio which should work with your monitor. Then power cycle all your devices: your game console or video source, your monitor and the HD PVR 2. When you power everything up again, the HD PVR 2 will report that it can only do 2 channel audio and you should now have audio from your monitor.

What kind of webcam can I use to make Facecam videos?

Hauppauge Capture uses any webcam, either HD or standard definition, as long as it has a 'raw' YUV or YUY2 mode. MJPEG and other compressed formats are not used. Your webcam can be 4:3 or 16:9. Popular webcams include the Microsoft Lifecam HD-3000 plus, if you have a laptop, the built-in webcam.

Hauppauge Capture chooses the most suitable video mode supported by your webcam. You can set the size of the video, and the format (4:3 or 16:9) in the Settings menu of Hauppauge Capture.

Can I record video from my old Nintendo, PS2 or Wii?

Yes. Connect the yellow cable from your console (Nintendo, PS2, Wii or any other game console which has a yellow composite video connector) to the Blue connector on the Hauppauge AV cable. Then connect the red and white audio cables from your Wii to the red and white connectors on the Hauppauge AV cable. Then, in Hauppauge Capture, select Composite under Video input and Line In under Audio input.

Here is a video which shows you how to use the HD PVR 2 with an Nintendo 64: http://www.youtube.com/watch?v=Mb541Ww09jg

Can I record high definition TV from a Cable TV or Satellite box or DVR?

If your satellite or cable box or DVR has Component Video connections on the back of the receiver (normally Red/Green/Blue or marked YPrPb), then the answer is 'yes'. By connecting the Component video output from your high definition cable TV or satellite TV set top box to the Component video inputs of the HD PVR 2 or Rocket, you will be able to record the TV programs coming from your set top box to the hard disk. Component video connections are normally the Red/Green/Blue connectors on the back of a set top box. Sometimes they are also called YPrPb or YCrCb connectors

If your cable box only has HDMI, you might need an HDMI to Component video converter. Here is a diagram on how this converter is connected.

What type of recordings can I make with Hauppauge Capture?

Hauppauge Capture supports H.264 recordings in the TS, MP4 and M2TS format. The video quality of MP4 and TS files are the same.

If you are recording from a USB-Live2, recordings are made in an MPEG-2 format.

What type of audio encoding is made in Hauppauge Capture?

If you are using the HD PVR 2 there are three ways of bringing audio into HD PVR 2: through the Line In (RCA) stereo audio jacks on the A/V connector, through the HDMI connector or through the optical audio connector (on HD PVR models with SPDIF support). When bringing audio in through the stereo jacks, audio is recorded as MPEG 1 layer 2 audio. When bringing audio in through the HDMI connector, the audio is also recorded as either AC3 or in MPEG 1 layer 2 format. Only HD PVR 2 models with SPDIF support will record AC3 audio.

If you are using the HD PVR Rocket or HD PVR Pro 60 recordings are always made with MPEG 1 layer 2 audio.

If I record my game play, can I uploaded it to YouTube?

Yes. Recordings made with Hauppauge Capture are either in TS, M2TS or MP4 formats, which can be immediately uploaded to YouTube without conversion. Hauppauge Capture records from HD PVR's in an H.264 form which is used by YouTube. And the Hauppauge Capture Edit tab allows you to trim your videos very quickly without the need to re-encode.

I see Hauppauge Capture can make screen shots. What is the size of those screen shots?

The size of the screen shots is based on your incoming video signal size. 1080p video screen shots will be 1920 x 1080 pixels.

Can I record my webcam while recording and streaming with the HD PVR 2?

Yes for recording, no for streaming. With the latest version of Hauppauge Capture, you can record your videos with a webcam in your recordings. This is called the 'Facecam' feature in Hauppauge Capture. Facecam allows you to specify the location and size of video from your webcam in your recordings.

I'm using a PS3 and I see a black preview screen in Hauppauge Capture. How can I fix this?

This happens if you connected your PS3 using HDMI and now want to use Component video so you can record with HD PVR 2.

To fix, you need to reset the video settings on your PS3. To do this:
- Make sure you have the HDMI cable disconnected on your PS3
- Then push the PS3 power button on the front of the PS3. You should see the light go Red. This means your PS3 is turned off.
- Then hold down the PS3's power button until you hear two beeps (one beep, then about 5 seconds and a second beep).
Your PS3 should now be set to Component video out and you should see video in the preview window in Hauppauge Capture.

How To Record Xbox 360 Game & Party Chat

• 1. Go to the Xbox Guide Menu
• 2. Go along to settings.
• 3. Select Voice.
• 4. Go down to voice output and select 'Play though both'. This will make the audio play out your TV and through your mic at the same time.

Depending on what game you are on, I highly recommend you turn down game volume as well as sometimes voice chat can't be heard because the game volume is too loud. However I guarantee that there will be a way to turn down your audio setting on whatever game you are on. Make sure you make it loud enough to hear, but quiet enough to make the voice chat clear and easy to hear.

I'm using Component video, but the preview window in Hauppauge Capture has incorrect colors

Most of the time this is caused by either one of the Component video connectors is not connected or you have swapped one of the colors. For example, if the Red connector is not connected correctly, your video picture will look green.

I see a change in brightness every few seconds in Hauppauge Capture and Hauppauge Capture while recording, streaming or playing back my video recordings. But my recordings are fine. What is going on?

If you are running an AMD graphics card in the PC which the HD PVR 2 is connected to, you may experience a slight change in brightness every few seconds while in the preview or edit screens. This is due to an issue with hardware acceleration that we have seen in some AMD drivers. This shift does not affect recordings and typically can be eliminated by either changing drivers for the graphics card or by disabling Hardware acceleration.

Video is jerky or broken up while capturing, yet my recordings are perfect. Why?

This is caused by either a slow processor in your laptop or desktop PC, or the display adapter is having a problem. Make sure your video card meets the minimum requirements. Also try updating to the latest drivers supplied by the manufacturer.
In September 2012, there was a problem with the ATI graphics driver which would cause jerky video or freezing of the video screen. This should be fixed with an update from ATI on their graphics drivers.

I get a black screen in the preview window when using Component video from a cable TV set top box.

Some set top boxes will disable or turn off the component output if the HDMI or DVI output is being used. Check to see how you have your Television connected to your set top box. You might need to disconnect the HDMI connector on your set top box when you want to record TV programs.

Audio pass through does not work

In order for the audio pass through to operate, you need to configure the Audio settings in the Hauppauge Capture application. Click on the Capture tab. In the Audio input section, choose your audio source from the drop down menu ( RCA, HDMI ). Once configured, the HD PVR 2 will retain these settings. Note: the HD PVR 2 must be powered on for the pass through to operate.

My video recordings look pixelated with fast motion. What can I do?

Increasing the recording bitrate will eliminate motion artifacts in your recordings. In Haupauge Capture, in the Capture tab make sure Variable is selected. Than start with Quality set to 11 Mbits/sec. This should give you very good quality. You can continue to increase the Quality up to a maximum of 14 Mbists/sec.

You can experiment with other settings, but in our experience, these are good for uploading to YouTube.

What resolutions and bit rates are supported using the HD PVR 2?

• Video record resolutions are 1080p30, 720p60, 540p60, 480p60 and a number of downscale variants of these formats.
• You can record at datarates from 1Mbs to 13.5Mbs. If you choose Variable, the maximum recording datarate is about 1.5 times the selected rate. As an example, if you have Variable selected and set the Quality to 14Mbits/sec, the maximum rate will be about 21 Mbits/sec.

How much disk space will Hauppauge Capture take when recording?

Approximately 2 GB per hour at 5Mb/s setting.
Approximately 4 GB per hour at 9Mb/s setting.
Approximately 6 GB per hour at 13.5 Mb/s setting.

Hauppauge Capture hangs during the installation. What can I do?

Check for the presence of 'Constant Guard' from Exfinity. If present, uninstall it, then re-run the installation for Hauppauge Capture. Once installed you can reinstall Constant Guard.

How can I record party chat from the Xbox One?

Here's a tip from an HD PVR 2 user:
'With the Xbox One, to record game commentary I do this: in Kinect settings, use the Kinect mic which forces the party chat to come out of the TV speakers. The Hauppauge game recorder will then pick up the party chat when recording game audio.

In order to record your voice (which won't come through the speakers and be picked up), you need to have a Mic plugged in to your PC and place near your face as you do. Then make sure in Hauppauge Capture you select the mic in the drop down menu and set level.

Then you will get the game chat and the game audio recorded, and you speak to your party via Kinect microphone. Basically, one mic to chat with your party and one mic to record your game commentary.'

Hauppauge Capture is not responding to the record button on my Rocket. How can I restart Device Central?

Device Central is a Windows service which monitors the record button on your Hauppauge recorder. Sometimes Device Central will close. If so, you can restart it by going to Windows Explorer and looking in ProgramFiles -> Hauppauge -> DeviceCentral and then running the program HCWDCTrayTool.exe

How can I adjust the color settings of my recordings

Hauppauge Capture, with most HD PVR recorders, can adjust the color settings of both the recordings and the passthrough video.

To adjust the color settings, open Hauppauge Capture and go to the Capture tab. Then click the Advanced button at the bottom and go to Video Proc Amp. Here you will see the color and briteness settings.

Warning: This page has been locked and archived on September 27, 2010. The official documentation for this card can be found at WinTV-PVR-500. This page remains as there is significant information herein not included in the official documentation. Please migrate any such information to the proper location.

• 3Troubleshoot Tips
• 4Common problems and solutions

The Hauppauge PVR-500 is PCI-based video tuner card which features hardware-accellerated video and audio compression. Technically the card is functionally identical to two PVR-150 cards on their own PCI bridge in one socket, and requiring only one coaxial connection for both tuners due to an internal signal splitter.

The card was marketed almost exclusively at OEMs and system builders and may or may not feature an 'MCE' designation in it's packaging. While there remains only one catalog number for the NTSC version of this card, Hauppauge did make several slightly different revisions of both NTSC and PAL/SECAM models of the PVR-500.

There were at least 3 different tuners used in the various revisions of the PVR-500. Some say that Philips tuner inside the older models has a better quality.

• Hauppauge WinTV-PVR 500 type A - Philips FQ1216AME MK4 TV tuner
• Hauppauge WinTV-PVR 500 type B - Philips FQ1236A MK4 TV tuner
• Hauppauge WinTV-PVR 500 type C - Samsung TCPG 6121P30A TV tuner

One notable exception to the apparent 'two of everything' behind this card, only the first tuner's FM tuner is usable for recieving terrestrial FM broadcast radio. For obvious reasons if your revision of the card supports an IR reciever or transmitter, there will only be one of each. Additionally, the US version of the card has a dbx-TV stereo audio decoder, while the European version of the card has a Nicam stereo audio decoder. As this card records OTA (over-the-air) analog video it is technically obsolete in the United States, however there exist separate PAL and NTSC versions of this card. Be sure the one you obtain is the correct one for your region.

All known versions of the PVR-150 are handled by the same version of the IVTV driver, now a part of the Video4Linux subsystem found in the 2.6.x Linux kernels.

Note: Hauppauge no longer ships any of the analog only (PVR) cards due to pressure from FCC.

The IVTV project developed a driver for this and the other Hauppauge PVR-xx0 cards which has become a part of the Video4Linux project and is now incorporated into the normal Linux kernel.

You will need a 2.6.x kernel (2.6.22 or newer recommended) to make this card work properly.

mythtv-setup, define 2 x PVR150

Select new Capture Card and configure the first card as a hardware MPEG-2 device like the PVR150 (Remember the PVR-500 is dual PVR-150's so you will need to configure two capture cards. The two cards will have the same tuner (which may be called tuner0 or tuner1, depending on your version of mythtv), but different devices (e.g. /dev/video0 and /dev/video1).

If you are lost; here are some screenshots of mythtv-setup for a PVR-500 in the Netherlands.

Driver refuses to load for mysterious reasons

Under certain memory configurations on 32-bit platforms, using this card's driver and some other drivers (usually but not exclusively nVidia's proprietary driver) at the same time requires more of a particular type of address space allocated than the kernel will allocate by default. If you experience the driver refusing to load for no obvious reason, check the output of `dmesg`. If you see either of the two following messages appear, you will need to go to Common Problem: vmalloc too small to learn how to apply a very small kernel configuration change which requires one reboot.

The messages to look for:

Kernel Recommendations

You need a 2.6.x kernel to make this card work properly. The drivers which work with the 2.4 kernel, even patched, are old and can no longer be expected to work reliably with MythTV 0.22 or newer. Using a kernel 2.6.29 or newer is highly recommended as this brings the kernel driver up to speed with the last release of the userspace tools (ivtv 0.4.0). Reports that you need to compile ivtv yourself outside the kernel tree can be considered old/obsolete information, as the ivtv driver itself completed the move into the kernel around version 2.6.26.

Spontaneous Reboots

Do not attempt to enable pre-emptive kernel locks in your kernel configuration--the ivtv modules do not get along with them and will cause spontaneous reboots.

Signal Strength Warning

Your cable feed usually only has enough drive power for 2 or 3 TV sets. If you're driving a large number of devices, you may need an RF Amplifier to boost signal strength. Conversely, your house cable may be supplying too much power to the PVR 500. Ivtv developers have noted that the Samsung tuners used in later PVR 500s are rather sensitive and will show a grainy picture if supplied with too high a signal level. In this case you must reduce signal strength by either inserting a 'pad' (a resistor) between the PVR and the cable, or if your house has a cable amplifier, by reducing the gain on the amplifier.

Outdated Repository

Additionally, installing current firmware and PVR150/500 specific audio firmware from the ATrpms repo using Jarod's:

does not provide you with the latest and greatest recommended firmware as the folks at ivtvdriver.org suggest.

While most of the people will ignore the ivtv warnings displayed by using:

related to buggy firmware... it becomes a big problem when you use the PVR500 in conjunction with the PVR350. (Presumably this happens with the use of PVR150 and PVR250s too, but I can't confirm that.)

Symptons include loss of audio on both the PVR500 tuners and inability to change channels. The PVR350(s) will work fine though. Follow the ivtvdriver.org people's advice and download, extract, and install the recommended firmware.

Motherboard Incompatibility

Those of you with the ASUS A8V board will be disappointed to know that there appears to be no way to get this board to work with a PVR-500 if you are using the AGP port. The PVR-500 has its own PCI bridge and the AGP port on the motherboard is also on a PCI bridge, and the second PCI bridge fatally confuses the BIOS when it goes to initialize the hardware for booting after the system inventory screen. The recommended (and only known) workaround is simply to replace your AGP video card with a PCI video card. One might also trade in the PVR-500 for a pair of PVR-150's, but since the PVR-500 costs more than a new motherboard that doesn't make much financial sense (cheaper to buy a different mainboard). Some other ASUS A8V-xx models are also affected by this bug, but can be made to work with a BIOS update. For other uses the ASUS A8V is a fairly nice board, and the PVR-500 is a fairly nice card, the board is just flawed in a way that makes it impossible to use anything with its own PCI bridge.

Audio Instability

There appear to be well-known and repeatable audio quality problems (everywhere you google) about Hauppauge PVR-xxx cards and MythTv. From weeks of Googling for help and testing combinations of IVTV drivers, Myth versions, kernel versions, hardware settings etc., I've come to the conclusion that Myth does not cleanly set (and reset) the audio channel on channel change, or system startup. ivtvctrl -q0 -d0, ivtvctrl -q0 -d1 repeated a couple of times temporarily corrects the audio problems (until next channel change). The problems may be timing-related in the API between MythTv and IVTV. I will be looking into the source to investigate the API issues between IVTV and MythTv. I'll post results. Currently running MythTV 0.20, ivtv 0.4.7, kernel (Ubuntu Dapper) 2.6.15-27-amd64-generic, PVR-500, Nvidia GeForce etc. No dmesg problems reported, no logged mythtv problems, no logged ivtv problems (ivtvctrl -D 99). To the software things look okay - to the listener, audio is clobbered.

More recent versions of ivtvctrl do not provide for the '-q X' option, and running the above commands will therefore return the usage screen and do nothing. The functionality has been moved to the v4l2-ctl program. A workaround that has been successful in some cases is to set the audio source to one where there is no audio, and then set it back to the source where the audio actually is. Assuming that the video capture device is /dev/video2 the following code would set the audio source to 0 and then back to 1:

As of ivtv-utils 1.2.0, the command is now --set-audio-input=0

As of this writing, the latest iteration of my channel changer is to change the channel on the STB and immediately change the audio input to one where there is no sound, and a few seconds later come along and change the audio input back to one where there the sound exists. Here is a sample perl script that does this with the directv.pl script. Of course adding logging, debugging, and error checking is a good idea. (The reason for the 'fork' is to let MythTV believe the channel is tuned, and then 'turn on' the sound once MythTV is capturing the feed and the set top box has actually tuned the channel.)

Unreasonably low latency

The following files in /var/log may contain a message 'Unreasonably low latency' from ivtv:

If you find such messages you should probably read the page on PCI Latency

No sound on first recording

I had the problem that the first time mythtv tunes to a channel (live-tv and recording) sound is not working. Changing channels fixed the sound. I had this problem with ivtv 0.4.1 and 0.4.2. After some help from the mailing list, I found out that executing

fixes the sound. I don't know what this command does. However, I had to manually issue this each time I tuned the first time with a tuner. If I execute ivtvctl a second time, I get a sound hickup. So only execute this command once if a tuner is recording. To ease my life, I created this script:

Only one coax input

Despite having two TV tuners, the PVR-500 has only one coax TV input. The card has two coax connectors, but only one feeds both TV tuners, using an internal splitter; the other allows connection of an FM radio antenna. Thus, the PVR-500 will allow recording two programs via coax from the same underlying source, but will not support two independent coax video sources. For instance, you cannot attach two cable boxes via coax and record independent programs; you must connect at least one cable box via RCA cables.
