If it's an XviD encode, you can just remove the fake DivX userdata when unpacking the bitstream. The XviD encoder only writes DivX userdata when packed bitstream is used. For a DivX encode, I believe you can either remove the 'p', or change it to 'n'.

The XviD userdata string is 'XviD' followed by a 4 character bitstream version (for example, XviD 1.0.1 writes the userdata 'XviD0035'). If the character 'C' is appended to the end, this indicates cartoon mode. The DivX userdata string is 'DivX' + version + 'b' + build ('DivX503b1031' for DivX 5.1.1), followed by a 'p' if packed bitstream was used.

EDIT: bond was quicker . Yeah, if you want to leave the fake DivX userdata string in there and just change 'p' to 'n' it won't hurt anything.
