I need to draw in front of a playing NSMovieView. I created a NSView subclass, and placed it over the NSMovieView. I "move[d] to back" the NSMovieView. It draws fine when I put an mp3 in the movie view, but when a .mov is playing, the image is superimposed over everything else. How do I draw in front of an NSMovieView? Not even a button, moved to the front, can be seen beneath it.

z-ordering isn't a fully-supported part of the NSView model -- note that the "bring to front" etc. options only exist in IB and can't be done programmatically -- so views which are peers in the view hierarchy aren't guaranteed to have the same z-order relative to each other all the time.

Generally, this problem can be solved by making the "in front" view a subview of the "in back" view. (Since IB thinks only certain NSView subclasses can be "containers", you'll have to do this programmatically.) However, hardware-accelerated video playing may muck with the NSView drawing model, in which case you might be stuck (or you might be able to solve the problem by dropping down to a lower API level).
