I'm using ALSA. How is it that it can capture and then output to my video card and monitor but can't achieve this with the sound? <BR>

through the soundcards line in (or CD in ports via a wire jumper) to get audio,
in this case you would need to be recording from the soundcard (/dev/dsp for
OSS, or /dev/snd/pcmC??? for ALSA) while grabbing frames. Some better TV cards
do have audio record ability with the btaudio OSS driver. (I donno if there is
a comparable ALSA driver..)
For DVD's you might look into dvdauthor.. I've personally never used it as I
don't have a DVD burner..
You might try the mpegtools package
