title: MPMoviePlayerViewController not appearing
body: <p>I'm attempting to load a small movie for a Title/Splash screen. However, when I call <code>presentMoviePlayerViewControllerAnimated</code> nothing happens. I have confirmed that the block of code is being executed, but there is nothing perceptible to the user. </p>
  
  <p>I am targeting the iPad, so 3.2 is assumed.</p>
  
  <p>Any help would be appreciated.</p>
  
  <pre><code>- (void)viewDidLoad {
    [super viewDidLoad];
  
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Intro" ofType:@"m4v" inDirectory:nil];
    NSURL *fileURL = [NSURL fileURLWithPath:path];
    MPMoviePlayerViewController *playerView = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
    [[NSNotificationCenter defaultCenter] addObserver:self selector: @selector(playbackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerView.moviePlayer];
    [self presentMoviePlayerViewControllerAnimated:playerView];
    [playerView release];
  }
  
  - (void)playbackDidFinish:(NSNotification*)aNotification {
    MPMoviePlayerController *player = [aNotification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                  name:MPMoviePlayerPlaybackDidFinishNotification
                                                object:player];
    [player stop];
    [self dismissMoviePlayerViewControllerAnimated];
  }
  </code></pre>
