[dvd::rip] Dvdrip gets the wrong audio channel, but plain transcode work

First of all, I would like to thank the developers of dvdrip and Transcode
for such excellent tools!  Linux is getting more good video apps...

Anyway, onto my small problem:

I'm using transcode-0.6.0pre2_20020115-1 and perl-Video-DVDRip-0.30-1.

When ripping a divx from a DVD with multiple audio tracks, I noticed the
file dvdrip produces is a different language track than the one I picked.
Strangely, running transcode manually produces the correct result.
Everything looks fine by the debug commands, however.  Perhaps a transcode
bug?

This DVD is a rental which I have to return tomorrow.  Hopefully I can
provide enough information now to be of some help.  It's "Hard Boiled"; the
distributor is Fox Lorber.  It's NTSC;  I live in the US.  The movie is
originally from Hong Kong, and is a bit different than the norm fare of
rentals.  It has 2 titles: the first title is a small distributor blurb,
with 1 audio channel, a AC3 2 channel.  The second title, the actual movie,
has 3 audio channels.  The first is a AC3 1 channel Mandarin track, the
second is a AC3 1 channel English track and the third is a AC3 2 channel
English track that contains director commentary.  I wanted the second
English channel.

Dvdrip shows all this information correctly, but no matter what I pick at
the Audio channel selector I always get the first channel, the Mandarin
channel.

>From Debug/Show Transcode Commands:

Probe Command:
==============
tcprobe -i /dev/dvd -T 2


Rip Command:
============
rm -f /home/doug/dvdrip/hard_boiled/vob/2/hard_boiled-???.vob;
tccat -t dvd -T 2,-1,1 -i /dev/dvd | splitpipe -f 
/home/doug/dvdrip/hard_boiled/tmp/hard_boiled-2-nav.log 1024 
/home/doug/dvdrip/hard_boiled/vob/2/hard_boiled vob | tcextract -a 1 -x ac3 -t 
vob | tcdecode -x ac3 | tcscan -x pcm


Grab Preview Image Command:
===========================
mkdir /tmp/dvdrip16192.ppm; cd /tmp/dvdrip16192.ppm; transcode -z -k -i 
/home/doug/dvdrip/hard_boiled/vob/2 -o snapshot -x vob -y ppm -c -1 


Transcode Command:
==================
transcode -i /home/doug/dvdrip/hard_boiled/vob/2 -x vob -a 1 -w 1470,250,100 -o 
/home/doug/dvdrip/hard_boiled/avi/hard_boiled-2.avi -c 0-175950 -y divx4 -V  -b 
128

The rip command looks correct to me. (?)

I used transcode directly with help from the homepage.  This did grab the
correct audio track:

nice transcode -i /dev/dvd -x dvd -a 1 -T 2,-1 -g 720x480 -M 2 -V -X 2,0 -Y 
80,8 -s 1.09 -o hard_boiled.avi -y divx4 -w 1293 -f 23.976 -R 2

I've used dvdrip before on another DVD with great success.  I'm sure the
trip-up on this DVD has something to do with the layout of the audio
tracks.
