XviD still supports "packed mode" for B-VOPs, which IIRC is the 
old DivX "compatiblity" mode. However, since DivXnetworks finally noticed 
what a bad idea it was to store B-VOPs that way, they changed 
their decoder themselves, so "packed mode" is now compatiblity for 
completely outdated DivX-decoders only, it should therefore not be used. 

In principle, any XviD encoded file should play with recent DivX as 
well, and to make it run on hardware players as well, you might have to 
not use Qpel and GMC.
