title: Why can't I retrieve UIDeviceOrientation correctly while playing a movie in MPMoviePlayerController?
body: <p>Everything works fine while I'm not playing anything (I'm calling beginnotifications, etc, and using the orientation to rotate my view). But after I start playing with <code>MPMoviePlayerController</code> everytime when I try</p>
  
  <pre><code>UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
  </code></pre>
  
  <p>The <code>orientation</code> gets a <code>UIDeviceOrientationUnknown</code>.</p>
  
  <p>Any clue?
  When the movie stops everything works alright again.
  I need this orientation to rotate the player's window, because Im using Iphone OS 3.1 so I can't directly use the view property inside MPMovie player controller.</p>
