We have all types of MOV files. Everything from pro res, DV and web files. None will play in Premiere or the Quicktime player (won’t open). It is a Quicktime Pro licensed version. Before we made it Pro, then the Quicktime player would open but files wouldn’t play. All will play in ITunes. We also have the Quicktime MPEG2 plugin downloaded from Apple and installed. This machine is an upgrade from Vista where Quicktime worked fine. I get an “ERROR 1856” when we try to play the MOV files.
I’m hoping someone from Apple will see and address this post?
