We don't use quicktime to decompress mpeg, we only let it do the YUV->RGB
transformation for us (since QT can use your graphics card hardware for this
job). So the reason for the crashes is burried somewhere in the vlc sources,
and it's not Apples fault. ;-)

I watches the first 10 or 20 minutes of the movie file I downloaded for you,
but didn't experience these hangs. If they always happen at the same
location, could you tell me the timestamp of this location?

Do you have a G3 or a G4? Maybe it's the altivec code on the G4 that crashes
on the "Coefficients out of bound" you saw... You could try to disable the
altivec-support with (from the Terminal):
./vlc.app/Contents/MacOS/vlc --motion motion --idct idctclassic <your movie file>
