title: MPMoviePlayerController playing movies in reverse (backwards) is not smooth in iPhone App
body: <p>I am developing an iPhone application where I need to reverse a video playback. I am currently using XCode 4.2. I am trying to play a movie in reverse with the MPMoviePlayerController.
  But when it plays in reverse it is not as smooth as playing it forward. It becomes a bit choppy and is not at all smooth. The following is my code.</p>
  
  <pre><code>- (void)viewDidLoad{
  //code for initializing the movie player
  MPMoviePlayerController videoPlayer = 
  [[MPMoviePlayerController alloc] initWithContentURL:"URL"];
  self.videoPlayer = videoPlayer;
  [videoPlayer release];
  self.videoPlayer.view.userInteractionEnabled = NO;
  self.videoPlayer.initialPlaybackTime = -1;
  self.videoPlayer.shouldAutoplay=NO;
  [self.videoPlayer prepareToPlay];
  
  
  //code for initializing the button 
  UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
  
  [button setTitle:@"Reverse" forState:UIControlStateNormal];
  
  [button addTarget:self 
  action:@selector(reverseMovie) forControlEvents:UIControlEventTouchDown];
  
  button.frame = CGRectMake(0, 0, 50, 40);
  
  [self.view addSubview:button];
  }
  
  -(void)reverseMovie{
  [self.videoPlayer setCurrentPlaybackRate:-1.0];
  }
  </code></pre>
  
  <p>What could be the possible solution to this?</p>
