Hi, I have recently upgraded to a new Mac Pro system and I want to be able to play Quicktime movies that I have rendered on my previous Mac, using the Media 100 codec. So I installed the Media 100 Transcoder but when I open the movies in Quicktime Player I get a white frame. I tried installing the Media 100 software codecs instead of the Transcoder, but the same thing happened. I thought it might be some conflict with Final Cut Pro components (I didn't have FCP on my old Mac) so I also tried removing all the Final Cut Pro codecs from the Library: Quicktime folder, to no avail. I'm sure someone else has encountered this problem and hopefully advise me.
The transcoder is outdated for some years. There are software codecs which can be downloaded from the website, but they are PPC only (you would need to run QuickTime player in Rosetta). Or you can buy e.g. Media 100 Producer which contains the Intel-native codecs.
