[dvd::rip] different audio tracks for different video tracks, dvdrip tak

Debian unstable, kernel 2.6.13.2, dvdrip 0.52.6, transcode 1.0.2, 
two-pass-encoding to mpeg4 and ogg.

Hello,

with some DVDs (mostly of older films, having several mono tracks) I get a 
problem in the "merging audio" stage. However, the problem is the second 
encoding pass which finishes almost immediately. I found out that although 
transcode doesn't really give an error when run from the command-line, the 
problem is the audio track.

The DVD I'm currently fiddling around with has about four audio tracks for its 
main video track; however, a different video track has only one audio track, as 
far as I'm able to see, and I think the problem is that dvdrip allows me to 
select from all four audio tracks for all video tracks. Thus, for a specific 
chapter, the wrong audio track is selected.

To give an example, this is the transcode command that dvdrip creates:
transcode -J smartyuv=threshold=10:Blend=1:diffmode=2:highq=1 -m 
/mnt/pandora/unnamed/avi/003/unnamed-003-00.ogm -R 2 -K -w 1199,50 -i 
/mnt/pandora/unnamed/vob/003 -y ffmpeg,ogg --print_status 20 -F mpeg4 
--a52_drc_off -B 24,26,8 -x vob -b 128 -a 0 -H 10 -o 
/mnt/pandora/unnamed/avi/003/unnamed-003.ogm -f 25

I found out:

(1) When I omit the "-a" option altogether, transcode shows in the informations 
it gives at the beginning, that it can't find "audio track 0". However, video 
encoding starts.

(2) The command line above (i.e. as dvdrip creates it) gives NO error in the 
information lines, but everything finishes after some seconds without any 
relevant errors. The created audio file has only some few KB.

(3) When I specify the audio track "-a 4", everything works, and there's real 
audio in the audio file. I think it's the only audio available for that track. 
FYI: dvdrip probed "0" to be an English mono audio track, and "4" to be an 
English stereo one.

(4) When I view the VOB file with a recent "mplayer -v", there's only one audio 
track shown, an English one (with the AID 131, but I think that's mplayer's 
nomenclature.

If I should post some log files, specify which ones. I didn't want to post lots 
of output that isn't relevant for you.

Have a nice day & thanks for the great work,
Cato Minor.
