ios - How to stop MPMoviePlayerViewController's automatic dismiss on moviePlaybackDidFinish?

An MPMoviePlayerViewController which is presented modally through presentMoviePlayerViewControllerAnimated: automatically dismisses itself when it's content finishes playing.

I've tried to disable this, since I want to play other content afterwards. However, even if I register to the NSNotificationCenter with [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerVC.moviePlayer]; and set some other content, it still dismisses.

How can I stop MPMoviePlayerViewController from automatically dismissing itself?

UPDATE:

As a clarification, this question is only about removing the automatic dismissal and not about dealing with the disabled 'done' button. The selected answer reflects. This is by design, since we assume the developer adds their own means of dismissing the MPMoviePlayerViewController. However, @bickster's answer deals with the 'done' button as well.

Thanks to this blog article I figured out that MPMoviePlayerViewController automatically registers itself to the NSNotificationCenter upon creation. You have to first remove this registration and it will stop dismissing itself automatically.

// Initialize the movie player view controller with a video URL string
MPMoviePlayerViewController *playerVC = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]] autorelease];
// Remove the movie player view controller from the "playback did finish" notification observers
[[NSNotificationCenter defaultCenter] removeObserver:playerVC  name:MPMoviePlayerPlaybackDidFinishNotification object:playerVC.moviePlayer];
