title: iphone MediaPlayerController does not show the media player
body: <p>HI, </p>
  
  <p>I am developing an app which contains 3 tab view control. One each for audio, video and images. </p>
  
  <p>When i select the video tab, I have all the items displayed in the table view format so that on selection of any cell, the video is shown. 
  Example.</p>
  
  <pre><code>(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
  
  MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:url]] ;
  
  [moviePlayer play];
  
  }
  </code></pre>
  
  <p>The problem with this is though I am able to play the video I am unable to see the video and can hear only the audio.
  In addition, if I were to close the app while the video is playing, and start it the app, the application crashes. </p>
  
  <p>Can you please let me know how should I go ahead ?</p>
