I had ensured perfect KVC/KVO compliance, and I was using the compliant accessors everywhere except for one place: the delegate's -awakeFromNib method where I create the Player object in the first place. I declared the property readwrite in the class extension and changed player = [[Player alloc] init] to self.player = [[[Player alloc] init] autorelease], and suddenly it all worked. (Though it vaguely annoys me that I have to add a spurious retain/autorelease to the Player object.)
You don't technically have to. You could do:
[self willChangeValueForKey:@"player"];
player = [[Player alloc] init];
[self didChangeValueForKey:@"player"];
