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.

Hi,

I had exactly the same problem & found the answer here https://discussions.apple.com/thread/3219982?start=0&tstart=0 . Download a program called Perian, very easy to download worked a treat. I wish all fixes were this easy 😉 - Debbie
