Video enters fullscreen but will not exit (iOS 6.1) - ios

Question

I am using a custom movie player to play videos with MPMoviePlayer as the base, and while the player will enter fullscreen fine when setFullscreen:YES is called, it won't exit fullscreen when setFullscreen:NO is called.
I have tried:
adding the video's view as a subview of a smaller window, and resetting the view's frame
using notifications as I show below (based on what I read in another question about this problem)
Here is the code I am currently using. None of the answers I have seen have solved the problem for me, so any help would be greatly appreciated.
- (IBAction)fullScreenPressed:(id)sender {
if ([self mediaIsVideo]){
if ([self.videoController.moviePlayer isFullscreen]){
[self.videoController.moviePlayer setFullscreen:NO animated:YES];
UIImage *full = [UIImage imageNamed:#"fullscreen-vector-icon.png"];
[self.videoFullscreenButton setImage:full forState:UIControlStateNormal];
}else{
//video is in fullscreen, add notification observer
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(exitFullscreen) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[self.videoController.moviePlayer setFullscreen:YES animated:YES];
UIImage *undoFull = [UIImage imageNamed:#"fullscreen-exit-vector-icon.png"];
[self.videoFullscreenButton setImage:undoFull forState:UIControlStateNormal];
}
}
-(void)exitFullscreen{
if ([self mediaIsVideo]){
NSLog(#"notification selector called");
[self.videoController.moviePlayer setFullscreen:NO animated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
}
}
