title: Movie is played with some delay after calling play on MPMoviePlayerController
body: <p>I am developing an iPhone application in which I play the videos using MPMoviePlayerController. Sometimes, some of the videos does not play immediately after I call play on MPMoviePlayerController.</p>
  
  <p>I have called prepareToPlay and in the notified method of MPMediaPlaybackIsPreparedToPlayDidChangeNotification, I am calling play on MPMoviePlayerController.</p>
  
  <p>How can I identify the problem here?</p>
