I recently upgraded my OS to Mountain Lion 10.8.2 and cannot open up .avi files now in Quicktime. These same files opened up with no problem prior to my upgrade.  Additionally, I had upgraded to the Pro version of Quicktime recently, but it appears I've retrograded back to the basic version, unexplainably.

 

I get this error message: The document “ANDREW_McD_MEDIA_VERSION.avi” could not be opened. A required codec isn't available.
