dvdrip refuses to work on my distribution.
mmh then there's the chance that tcdemux & tcdecode won't work either. -
usually you get those as dependency to dvd::rip. - see.

I'm sure that you can also use mplayer/mencoder or some ffmpeg command
line to do the same job.. gstreamer too..
Is there a chance you could
tell me what the tcdemux | tcdecode scripts would be to extract the audio?
sorry, I did not have my dvd drive with me.. now I do.
how are your command line skills? dvd::rip does a lot of fancy piping (
`man tee` -> man dvdrip-multitee ? :) ) - the command that does ripping
& demux is several pages long (includes 100 subtitle commands)...
It boils down to sth like this:
tccat -t dvd -T 1,-1,1 -i \/dev\/scsi\/host8\/bus0\/target0\/lun0\/cd |
tcextract -a 0 -x ac3 -t vob | tcdecode -x ac3 | tcscan -x pcm
adjust the device to match your DVD-ROM. and replace the last step " |
tcscan -x pcm" with " > ripped-audio.pcm" to write the audio into a
file; or use " | tee ripped-audio.pcm | tcscan -x pcm" to write to a
file and scan for peak values..
use sox or rezound or ... to convert the pcm into your favorite format!
good luck,
