That's what I thought too, but that's not actually the case. To keep things simple, the MovieController is attached and both the Movie and the MovieController are set to the same port. Despite this, MCDraw will draw the movie but not the controller-bar.

Since MCDraw isn't doing anything useful, the answer seems to be just to forget about it. The best suggestion for getting the entire MovieController to redraw itself is to call MCInvalidate followed by MCIdle. It seems like a bit of a hack, but it does work reliably.

Yes, I discovered this the hard way when I first started doing OS X development. For seventeen years I had happily been assuming that WindowPtrs and GrafPtrs were interchangeable, and suddenly they weren't. It was quite a traumatic discovery at the time.
