Installation and configuration notes
These cards come with an external audio pass-through cable. This makes the number of different installation options actually three:
1) Use the card in combination with its audio pass-through cable. The card itself uses the bttv driver, and the audio comes from your soundcard's line-in connector.
2) Use the card without its cable. Use the bttv driver for the video, and use btaudio driver on your Open Sound System (OSS) based linux box.
3) Use the card without its cable. Use the bttv driver for the video, and use snd-bt87x driver on your Advanced Linux Sound Architecture (ALSA) based linux box.
Actually, only the 2nd and 3rd option are useable for MythTV. Most modern linux distributions use the ALSA audio implementation as OSS is declared obsolete. So if you are building a new MythTV box, you better use the 3rd option.
Most modern linux distributions will automagically load these drivers; otherwise, visit the driver pages on this Wiki!

When setting this card up following Jarod's Guide, I was only able to get mono audio when capturing/recording. Playback using xawtv resulted in stereo output, but take note, playback is different than capturing.
In order to get stereo capture working, I had to do the following:
# yum -y install alsa-lib # yum -y install alsa-lib-devel
After that and a quick reboot (I'm sure just a reprobing of the sound card would work...) the capturing is now in stereo.

Not sure if "chroma_agc=1 pll=2" are needed.. I found them from some web posting. NOTE that WinTV Go comes in several varieties: you need to experiment type and tuner options.
Useful links I found:
And dont forget this important section from Jared's Mythtv on FC4 document:
And relevant WinTV GO/bttv snippet from dmesg:

User Experiences
If you have this card, speak up! This is a good place to note your experiences - ease of install, what you like, what's not to like, etc.
- I have a WinTVGO w/FM. Works great with myth, but it uses the bttv module and the snd_bt87x module to get audio directly off the card. This is much better than using a sound card input. To clear up permissions problems with the module on Fedora, I've modified the mythbackend startup script with these three lines, before starting myth.
mknod /dev/video0 c 81 0 && chown mythtv /dev/video0 && chmod 600 /dev/video0 modprobe bttv modprobe snd_bt87x
- Scott Carlson
I have this card without the FM tuner. I am brand new to Myth and I have set it up on Ubuntu LTS Desktop. So far I have had to install the Nvidia drivers and set the correct card type.
modprobe bttv card=10 tuner=auto
Now I am getting a green screen, but I am seeing something. I have a bit more to learn about this so I am not giving up yet :)

I have seen many bt87x based cards, both with FM and without FM. In fact, the table on top of this page now lists the correct drivers, so just load the drivers and GO!
Only issue I have seen with these cards in combination with some slower systems is the lack of synchronization between audio and video in the capture.
Therefor, I switched to the Hauppauge WinTV-PVR series with onboard hardware MPEG encoders... --Michel 08:55, 17 April 2007 (UTC)
Some (all?) of the FM-less WinTV-Go cards use the BT848 video capture chip, and do not have audio capture capabilities. These cards are not suitable for Myth, based on the configuration options listed at the beginning of this page. The only info shown by lspci for my WinTV-Go card is:
02:0b.0 Multimedia video controller: Brooktree Corporation Bt848 Video Capture (rev 12)

I have tried the WinTV Go card (with FM, without remote) and I managed getting it to work with MythTV. According to the first section on this page it should be possible to get this card running with sound without the cable that connects the line-out of the card with the line-in of the soundcard, but this was not possible with my tv-card/soundcard-combination. I have a MSI Media Live System that has an onboard sound and no matter how I tried in the last four days of hacking I coudn't manage to get sound without the cable. I think it depends on the WinTV Go card which is really old - I think I bought it back in 1999...
When finally using the cable I had sound - but the quality is very poor. It has also been poor on Windows back in early 2000 when I used it then. But now it's so poor that I decided to buy a Hauppauge PVR-250 card on ebay that encodes the sound with the video. Got it for roughly EUR 30. I hope the quality is better that way and I'll not have any more problems.

The audio on these cards will not work with mythtv or with tvtime. I have searched and tried a few workarounds. A pass through cable or the external sound jack is the only way to get audio, but this will not sync well for mythtv. Here is the bug report, https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/29789 It seems that kernels after 2.6.15 all have this issue. I would not try any bt87x card with mythtv until this bug is resolved. There are WinTV models that do work, WinTV-Go with FM is not one of them. Don't waste your time or money, especially when you can pick up a hauppauge pvr 150 for $40.

I have had no trouble with the WinTV (bt878) cards under Mythbuntu 8.04. I'm using a pair of them, and audio on both cards works fine without the need for pass-through cables. Live TV and recording works equally well in regards to picture quality and sound. The only real effort required to use these cards was the need to alter the brightness, hue, etc through mysql in order to eliminate washed-out looking picture quality.
-- KAdams4458 20 May 2008
I have had no problems with my WinTV Go tuner using the sound pass-thru cable to my sound card's line-in. Both Feisty and Hardy detected and installed the required drivers. I've been using it in a combined FE/BE system for 18 months.
