That worked (good) except for a new issue (bad). The composition overlay is for a QuickTime movie and where the composition covers the movie view, the playing movie will only show as black. Is there a way to get QC to overlay a QT movie?

QuickTime in Tiger now use Core Video for displaying the movie, so it goes through OpenGL as well. I guess there is some kind of conflict: you would need to put the QCView in a separate window, as a child window of the movie window and on top of it. Then make the QCView window transparent -setAlpha:0.9999 and -setOpaque:NO or something like that. You might also need to set the background color of the QCView window to [NSColor clearColor]
