title: MPMoviePlayerController multitasking problem
body: <p>I develop an application on iphone that uses MPMoviePlayerController to play audio file.
  When Application goes to background, if mpmovieplayer is playing, iphone continues to play the current music, but when it ends, the next track doesn't start.</p>
  
  <p>I try to start the next audio file in the MPMoviePlayerPlaybackDidFinishNotification and when I follow the code using the debugger I can see that the method is invoked and the code executed, bat the next audio file still doesn't start.</p>
  
  <p>Is this possible on iOS 4.1 or this is a limitation?</p>
  
  <p>Best regards
  Samantha</p>
