Also have noted that some videos only will play once. Only way to get them to play again is to close them and re-open them.
Unable to duplicate this problem also.
There is no "report bugs" in Quicktime. Posting to the feedback link has been done.
I stand corrected. Was typing a response in Safari and saw its "Report Bugs to Apple..." option and thought I was still in QT app. Sorry!
I have also noticed that Apple definitely reades these forums and reponds to them.
Apple personnel may or may not read any particular forum at any particular time. However, the only time I've seen them participate in discussions is when kicking off a new discussion area and they use a dedicated individual to answer initial questions. Once "the ball is rolling," such individuals tend to disappear from the discussions. Feedback, bug reports, and enhancement requests are the official means by which Apple responds to user requests/input. While they usually do not respond to each input on an individual basis, it is not at all unusuall for them to contact individuals requesting further information or sample files demonstrating a particular problem.
