Hi all,

I have a problem with transcode.
I'd like to get the raw AC3 audio from the vobs without the video frames so I 
can merge it into the movie later.
Sadly, transcode always gives me an empty 0 byte file as the result.
I ripped the vobs to disk from a DVD and they contain all the audio streams.

Here is what I do:

transcode  -H 10 -u 50 -a 1 -y raw -m 
/home/markus/Raw/unnamed/avi/003/unnamed-003-02.ogv -o /dev/null -x null,vob -i 
/home/markus/Raw/unnamed/vob/003/ -f 25.000 -A -N 0x2000

Does anyone have any idea where i went wrong?
