2 Capture card questions

Is there a list somewhere of tv capture cards that are known to
work with btaudio? For instance I have 2 Hauppauge cards,
a Win TV-PCI 404 (the non-stereo, non-fm model) and
a Win TV-PCI 401 (the stereo/FM model).

I have not been able to get the 404 to work with btaudio,
but the 401 stereo model works very well. And the sound
quality is SO much better than using a sound card.

2nd question...
There are several specs I've seen that the same WinTV series
only has capture resolution of 320x240. I can't say I know
for a fact if this is correct in Linux or not. Does anyone know
for sure. I know I can set myth higher, but is the card really
giving the higher resolution?

Now I'm shopping around for a good mate to the 401 card,
but hopefully with full resolution support and btaudio.
And now combine these two, any recomendations for a good
btaudio supported card with full 640x480 NTSC capture resolution?

Thanks,
Brian

I was under the impression that *all* bt878 cards could capture at
720x480, given a proper set of drivers. I know that my ATI TV Wonder
could only do 320x240 with ATI's capture software, but using WinDVR (or
Linux) let me do full res.

I'd say pump the res up in MythTV and see if the quality increases or
not.. it should be evident right away if you're getting 4x the
resolution or if it's just scaling up 320x240. I'd bet that under linux
you cards should do higher res.

ATI's card has worked fine for me under linux, so as long as you don't
need it for Windows use I'd recommend that as another alternative.

AFAIK that is correct.

In Setup->Playback, turn off Fixed Aspect Ratio then during
playback, press "f". The picture will be in a window the size
of the original recording dimensions.
