On my PC, I could import Xvid/DivX encoded files just fine into Premiere Pro CS3. (even .vob files) Now on my MBP, I haven't been able to import any kind of avi file that is encoded with Xvid. I get the same error message of "unsupported compression format". I'm not sure why, I had both codecs installed. I followed the steps listed here to install Xvid on my Mac. xvidmovies.com/mac (I copied the xvid component into the Quicktime library. Videos play back fine outside Premiere but no luck importing them into it.) Did I install it correctly? Or is there another installation directory that would enable xvid or divx and even .vob file videos in Premiere Pro CS3?
