I'm trying to encode a video file for DVD, but when I export it from FCP 4.5 to Compressor (version 1.2.1), Compressor won't start up. It bounces once in the dock and vanishes with nary an error message. Same thin happens when I try to start it independent of FCP. I tried reinstalling it, but I didn't have any luck. I'm running 10.4.3 on a dual 1.8 G5. Anyone have any ideas? Does this have anything to do with QuickTime 7?
