title: MPMoviePlayerController background color won't stick
body: <p>I'm trying to change the background color of my MPMoviePlayerController, and I can't get it to stick.</p>
  
  <p>I'm using:</p>
  
  <pre><code>moviePlayer.view.backgroundColor = [UIColor redColor];
  </code></pre>
  
  <p>I can see the background flash red while the video is loading. As soon as it is loaded, the background goes black again. I've tried setting the color after playback has started, but that has no effect.</p>
  
  <p>I'm using iOS 5.</p>
  
  <p>Edit: I'm actually attempting to set the background to [UIColor clearColor], not red. I should have asked my question properly in the first place.</p>
