I have been having a lot problems with exporting from iMovie. I have a 30 minute movie that I want to compress to a file around 400~500mbs. I found the best results with Divx and .Avi files. Unfortunately, after I installed Tiger, I noticed that the audio was faster than the video, like " old kung-fu movies ". I read in other forums that there are many problems with Divx compatibilty with Tiger. Whie waiting for a new version of Divx, can anyone give me some advice on the best way to export a movie from iMovie( good audio and video quality) thanks in advance!!
