Hey Guys, I had the same problem, and I tried every recommendation. So, I gave in and called the smart people at apple. 🙂, He made me delete some files.Here they are:
P.S. Get ride can mean move to desktop or trash (don't trash until you know it worked)
Go to finder
*Serve-Library-Quicktime-(then get ride of anything
But ApplIntermediantCodec.component, and AppleMPEG2Codec.component)
*Home-Library-caches-com.apple.idvd- (get ride of ride of it all)
*Home-Preference-(get ride of com.apple.IDVD.plist)
I hope this works.
Ben
