Mark Christiansen, whose new book Adobe After Effects CS 3 Professional Studio Techniques is nearing release, posted Fun with Gamma and Quicktime which briefly touches on file display issues in various apps. Hopefully Mark, as well as Trish and Chris Meyer, will have much more to say on the subject of color management in their new books and web postings.
An earlier post here, FreshDV notes Apple's 'color compatibility', attempted to summarize the same issue from the armchair.
Update: on the AE-List 3 Nov 2007, Chris Meyer alerted users to a not ready for primetime link to that should clarify things,
"... will be updated _significantly_ in the next week or two with specific instructions of what to do in various situations, and what to expect as a result."
