And it is still buggy on osx.
I agree iMovie needs either a version 3, or my idea iMovie Pro. Either way feel free to export to MP4 now, using the advanced button. QuickTime is just supported, so once it's supported apps instantly get the new advantages. The OS X finder can play MP4 movies for example, or how with OpenGL it's the same deal. When OpenGL came out with altivec support everythign ran 30% faster. Ahh, the good old days of 30% speed boosts. Now we all clamur after 10%....
Oh yeah, so if you have QuickTime6 you can export to MP4 from any app (QuickTime player, iMovie, FinalCut, After Effects, whatever) and apps that use QT as their basis (FCP for example) will also run faster due to QT6 speed boosts.
