I have experience with an ATI card (the TV Wonder, I think) and it has
been great under Linux. I use it with my game consoles for making screen
grabs and playing when the TV is otherwise disposed (i.e. Mandy's
watching something).

I haven't used it for output (not sure if my card does it), but I have
made movies using streamer/xawtv and have been pleased with the ease of
use, from the command line.

One hint I can give: don't forget to switch your system to take audio
input from the line-in (not microphone) if you're recording audio and
video. That drove me crazy. I ended up setting this through the GNOME2
audio mixer.

Also, if anyone knows: I can't get the MPEG encoder to deal with video
recorded at anything but 24fps. What's up with that? I can dig up the
error if someone wants, but it's really unusual. Something about a pel
ratio.

At 24fps, it's not bad, but video games with fast moving objects can
show a jerkiness that's unfortunate.
