Answering my own question.
I added an override for -(NSMenu*)menuForEvent:(NSEvent*)theEvent;, just
stubbing it out, doing nothing, returning nil.
It works out fine and seems to solve my problem.

Still, I'd be curious if there might be any further subtle behaviors I need
to override/stub-out for QTMovieView so that it's purely "watch only".
Thanx.
