Metti semplicemente i codecs nella directory /usr/lib/win32. Se non fosse presente la directory win32, non devi fare altro che crearla.
I codecs li trovi sul sito di MPlayer: in questo modo puoi riprodurre non solo divx, ma anche xvid, mov, rm, wmv etc....
Questo è il contenuto della mia directory win32:
