So are you playing different multiple movies or the same movie at different time indexes? Or are you playing the same movie in different layers and just want them in sync (e.g. reflection layer). If you are talking about the first case, I don't think there is any way to do this with QTMovieLayers. If you are talking about the second case (same movie and time), then as of QuickTime 7.5, you can do this. I blogged about it here and have sample code (doing reflection layers): http://playcontrol.net/ewing/jibberjabber/quicktime_75_core_animation.html -Eric _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
