You shoudl be able to use grabber programs like xawtv or even software
encoders like ffmpeg and others that use v4l. I guess with the drivers
for the 2.5.x kernels you can also use v4l2 which may help to get
better results if you want to grab movies. You can also use mencoder,
I had some success with the following options:
mencoder -tv on:driver=v4l:width=480:height=576:adevice=/dev/dsp:forcechan=2:outfmt=yuy2
-ovc xvid  -vop pp=lb  -oac mp3lame -lameopts cbr:mode=0:br=128  -o output.avi

Be sure to have mplayer compiled with all the necessary libs and you
need a fairly fast CPU.
