Problem confirmed.  It appears that the mpeg4 stream headers have the
correct information.  I'm not sure if the MOV headers are broken or if
there's a bug in the demuxer.  If the problem is indeed in the
demuxer, I'll blame quicktime brain damage for making it so darn
impossible to cover all cases.  Mike, would you like to say anything
in defence of quicktime?
