I just discovered that it works when the Audio Output preference is set to Stereo. It crashes when it is set to 4-channel, 4.1-channel, 5.0-channel, 5.1-channel and AC3. I can get it to start the DVD in stereo and then change the audio output to 4, 4.1, 5, 5.1, AC3 but the sound is terrible in these other; it sounds like a scratched CD.

Thanks for your bug report.

I notice that you seem to use the oss output plugin. May I ask you why? Could you please try the alsa output plugin as well?

I didn't realize that I was using OSS. My .xine/config has the following
entry:

# audio driver to use
# { auto null alsa oss arts esd file none }, default: 0
#audio.driver:auto

And I guess that xine picked oss over alsa? I would much prefer the use of
alsa.

I updated my system since reporting this bug and now I can play DVDs in 4
channel audio without crashing.

The following packages were updated:

totem-xine_2.18.0-0ubuntu1_i386.deb
