Hello!
I always use mplayer for that:
mplayer -vo null -dumpaudio -dumpfile output.mp3 intput.vob
works like a treat. Maybe you could even use mencoder or ppossibly the
ffmpeg utility or whatever it was they suggested at the time for extracting
audi from youtube.
If you want a different format than mp3, something like this might do the
trick:
mplayer -ao pcm:file=tmp.wav -vo null input.vob
And then encode the tmp.wav to whatever you like. It's also easily
scriptable.
You will only get seperate songs out of that, if they are stored in seperate
.vob-files.
I have written a script to trim recordings from radio. With a slight
adjustment that script will work for videos as well. It relies on you
listening to / skipping through the input and marking times. It uses ecasound
to do the trimming.
Hope that helps.
ciao
Julien
