Playing AVI files on Snow Leopard

[vbmike73]

I am running Snow Leopard on both an iMac and a MacBook Pro. On the MBP I can play an AVI file. On the iMac, I cannot. I get an error saying "The document “xxxxx.avi” could not be opened. The movie is not in a format that QuickTime Player understands."

What could be different between my two machines?

System Preferences > Other > Perian on the Mac capable of playing .avif files maybe?

Perian gives QT capability to play .avi files, there is also VLC Player, Movist and MPlayer OS X to play .avi files.

Awesome. You guys nailed it. I noticed the Perian on the MBP a few times, and I knew I had downloaded it for some reason, but it was a while ago, and I had forgotten what it was. I just DL it and problem solved. Thanks!!
