Why the msmpeg4???

I use full size capturing with mencoder (and denoise3d/hqdn3d for
reasonable compression) with mjpeg and mp3. Afterwards you can convert
it anything you like, including mpeg4 and mpeg2 (slow!).

Seems like the video input is not switched properly. This is the only
thing that differs between different cards. Apparently the default is
not "tuner in" on your card.

Did you start capturing with xawtv?

Look at the saa713* (!) homepage. From the top of my head it's
bytesex.org, but you may have to google. Not simply every card is
