mencoder

mencoder is great for doing this sort of work. It takes options to do
all sorts of video conversions and recordings including capturing from
TV and converting DVD videos.

DO NOT USE UBUNTU! Like so many programs I have found in Ubuntu the
mencoder program is broken. The mencoder that comes on the KnoppMyth CD
out performs Ubuntu. The Ubuntu mencoder converts video at about 9fps on
my computer while the KnoppMyth version often hits 78fps.

Here are some example commands for mencoder

To convert a DVD
mencoder dvd:// -ovc xvid -xvidencopts bitrate=2000   -oac mp3lame
-lameopts vbr=3 -aid 128 -o output.avi

To record TV
FRAME_SIZE="width=352:height=240"
BIT_RATE=2000
TV_DEVICE="-tv driver=v4l:device=/dev/video0:
$FRAME_SIZE:fps=29.970:norm=ntsc:chanlist=us-cable:channel=
$CHAN:saturation=-20:contrast=-20:audiorate=48000:immediatemode=0"
VIDEO_OPTIONS="-vf denoise3d"
AUDIO_CODEC="-oac mp3lame -lameopts fast:preset=medium"
#VIDEO_CODEC="-ovc lavc -lavcopts vcodec=mpeg4:vqscale=4:aspect=4/3
-ffourcc DX50"
VIDEO_CODEC="-ovc xvid -xvidencopts bitrate=$BIT_RATE"
mencoder tv:// $TV_DEVICE $VIDEO_OPTIONS $AUDIO_CODEC $VIDEO_CODEC
-endpos $DURATION -o "$FNAME"_`date +%m%d`.avi -quiet
