Robb is right about the trial version of Calibrated. It works well, but remember the trial version only plays 30 seconds. I had it on a classroom computer and was reviewing some AVID dailies in a class and asked why they cut in the middle of a scene.
This codec issue today is huge. Every camera manufacturer has their own wrappers and way with dealing with compression, making it very hard for any company dealing with codecs to deal with universal playback. That is why AVID has spent so much time with their codecs and wrappers. Calibrated solves most of the issues with CATDV and codecs. The only exception are some of the Sony F series cameras. Those camera codecs need to be repackaged or flipped. AVID will do it just fine but it takes more time as it is not take advantage yet of multi-core processors. Other compression software such as Sorenson Pro is written for multi threading but does not pass timecode. And not passing timecode is a deal breaker.
