I feel somewhat embarassed at asking this (as I used to be very up on Mac video software and what not) but here goes...
I am trying to watch some .avi files on my Powerbook with Quicktime 5 pro.....however it tells me that it does not have the right compression files...and I cannot d'l them.

So what to do? Is there another program I can use to either convert these files to .mov or .mpg (.mov prefered), or to view them? I am running 9.2.2, but I have OS X, does that make a difference? I don't think it should, but maybe it does.
