I have the same problem here (actually I reported it before and also uploaded 
a file with similar name;)), but seems nobody cares), recently there is a 
thread "bframe bug report" in xvid's list about this problem. And they said 
that the message is right and not a bug. But I don't know there is still 
those visually problems you mentioned exist if it's not a bug.

BTW, some of my friend tell me that sometimes the image even broken when play 
those xvid video with packed bitstream, using lavc. xvid cvs can handle those 
files with no problem of cource.
