I'm sure alot of you already know what my question is, but i'll ask it anyway. How do I get a .avi file to play in quicktime without it saying theres missing components. On my Dual G4 tower I can play them just fine, because I installed some component a year or so ago, and I forget what it was, and how I did it. Help. I can't play any avi files on my brothers intel iMac!!! Thanks.
