Now that I know your a MAC and not PC then I would say Perian ,but you tried that so I don't know anything else to help.
You could have to many codec packs and they would interfere with each other.
Have you updated to the newest Divx version?? It may help ??
Or just use VLC , or wait for a Mac user even tho they use Perian.
