title: Why isn't the scalingMode of my MPMoviePlayerController being respected when coming back from Full Screen?
body: <p>I have an instance of MPMoviePlayerController that is correctly displaying a HLS video stream on Portrait mode and also on Full Screen when I rotate my iPhone to the Landscape mode for the first time. The issue happens when I come back from Full Screen: the scalingMode property of my MPMoviePlayerController is still set to MPMovieScalingModeAspectFill but the video is displayed as it is set to MPMovieScalingModeAspectFit.</p>
  
  <p>Before adding its view as a Subview (self.moviePlayer.view) of my View (self.movieView) I set its scalingMode to MPMovieScalingModeAspectFill and everything works fine untill I exit Full Screen.</p>
  
  <pre><code>- (void) play
  {
      self.moviePlayer = [[MPMoviePlayerController alloc] init];
  
      [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidStart:) name:MPMoviePlayerLoadStateDidChangeNotification object:self.moviePlayer];
      [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];
  
      self.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
      self.moviePlayer.contentURL = videoURL;
      self.moviePlayer.controlStyle = MPMovieControlStyleNone;
      self.moviePlayer.shouldAutoplay = YES;
      self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
      NSLog(@"%ld", (long) self.moviePlayer.scalingMode);
  
      self.moviePlayer.view.frame = CGRectMake(0, 0, 320, 180);
  
      [self.movieView addSubview:self.moviePlayer.view];
  
      [self.moviePlayer setFullscreen:NO animated:NO];
  }
  </code></pre>
  
  <p>When I return from Full Screen it is set to the default value (MPMovieScalingModeAspectFit) and I can't change it back to MPMovieScalingModeAspectFill even if I explicity try to when I receive the MPMoviePlayerScalingModeDidChangeNotification.</p>
  
  <pre><code>- (void)movieScalingModeDidChange:(NSNotification *)notification
  {
      self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
      NSLog(@"%ld", (long) self.moviePlayer.scalingMode);
  }
  </code></pre>
  
  <p>The weird thing is that that this NSLog gives me:</p>
  
  <pre><code>-[CameraViewController play]:2
  </code></pre>
  
  <p>Which according to the Documentation is the enum for MPMovieScalinModeAspectFill, but the video is not it this aspect mode.</p>
  
  <pre><code>typedef enum {
     MPMovieScalingModeNone,
     MPMovieScalingModeAspectFit,
     MPMovieScalingModeAspectFill,
     MPMovieScalingModeFill
  } MPMovieScalingMode;
  </code></pre>
  
  <p>Has anyone experienced this same issue? Thanks in advance!</p>
