I just upgraded my linux distribution to Ubuntu 10.04 and transcode
"upgraded" from 1.0.2 to 1.1.5.  In 1.0.2, I used to be able to
preserve the AC3 audio track in a vob file when transcoding to xvid by
giving a command like:

   x=File_Name; transcode -i $x.vob -o $x.avi -y xvid -Z 640x360 -R3
-w5 -H200 -A -N0x2000

Now this generates an error:

[audio_trans.c] critical: Sorry, only PCM audio is supported for processing

In fact, I seem to get this error on every frame -- which makes me
think that this is a bug.

If I add the option -P2,

   x=File_Name; transcode -i $x.vob -o $x.avi -y xvid -Z 640x360 -R3
-w5 -H200 -A -N0x2000 -P2

then I get the error
[transcode] critical: audio format not supported by import module
[transcode] critical: failed to init import modules
[transcode] critical: plug-in initialization failed

Both used to work in 1.0.2.  How do I do this in 1.1.5?

(PS: Using -y xvid,tcaud has the same errors.  Leaving off the -A
removes the error messages but causes transcode to re-encode the
audio, reducing it from 5.1 to 2 channel.)
