liegt vllt daran das du divx nicht instaliert hast...

geh mal auf www.divx.com und lad dir das ding runter.

Mit dem VLC player kann man alles abspielen und kann man kostenlos downloaden.
Einfach mal bei google vlc player eintippen.

Nimm den Klite Codec Pack und dein Rechner kann wieder so gut wie alles abspielen:

Hier downloaden
