The movie seems to play fine in mplayer; so I think it is a problem with the player rather than the import. I turned verbose logging on and tried to play it again.  The results are below. Anyone have any ideas?
I can't help you there, but I've found that some DVDs have really, 
really bizarre encoding.  I've got one now that will reliably crash 
mencoder with kenrdeint for deinterlacer, but will barely encode with 
pullup, with tons of duplicate frames.  Normally that's a sign of frame 
rate being off, but not in this case.  It's just a really, really bad 

So it may just be the encoding on the DVD.  What does mplayer -identify say?

Also, try mencoder to transcode it; it may be the best alternative.
