title: can we add mpmovieplayerviewcontroller as a subview?
body: <p>I want to play a video on a same view on a button click.</p>
  
  <pre><code>NSURL *movieUrl = @"Some Url";
              CGRect frame;
              frame =CGRectMake(10,10,100,100);
              MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieUrl];
              [self.view addSubview:player.view];
              player.view.frame = frame;
              [player release];
  </code></pre>
  
  <p>when I run this, it shows a frame with black background but does not play the video. I am not using youtube video.</p>
