The crash happened right at the end of a movie or show, though not at 
the end of the VOB, right? Did you concatenate a bunch of titles? I've 
observed that the last chapter of a DVD title is usually empty. Maybe 
it's just an end marker. I've also observed the crash you had, usually 
right at the end of the movie. Coincidence? I don't think so.

I usually specify -endpos with a time just slightly short of the actual 
movie time. Alternatively, it might work to avoid copying the last empty 
chapter of the title. Since your crash didn't happen at the end of your 
VOB, you may have to encode each title or chapter composing that VOB 

I did encode one normal length movie that had such a discontinuity right 
in the middle. It actually changed aspect ratio from one scene to the 
next. I can only assume it was a mistake that was ignored by most DVD 
players. When playing the movie from the DVD, MPlayer got confused at 
that point and had no video from then on. Xine changed the aspect ratio 
of its window, but never changed back, so everything looked stretched 
from then on. When encoding it, I had to use GOPchop to get two separate 
VOBs and encode them separately.
