DIVX isnt in the AVI / wav spec,
http://wiki.multimedia.cx/index.php?title=AVI
http://www.rfc-base.org/txt/rfc-2361.txt

neither are the other 400+ codecs we've painstakingly compiled 
http://wiki.multimedia.cx/index.php?title=Category_talk:Video_FourCCs
or the unregistered twoccs we've found:
http://wiki.multimedia.cx/index.php?title=TwoCC

so we (ffmpeg) either supports DIV3, DIVX, XVID and FMP4 along with all
other 'non official' codec fourccs , or we dont.

i dont see any difference between 3rd party codecs in flv or avi or mov.
same thing happened with ogg and mkv. you cant block people from adding
codecs (vorbis in avi), you can only try to mitigate the disaster
(vorbis in avi) and decode existing samples.
