Cómo reproducir video en ios6

Estoy confundido acerca de:

MPMoviePlayerViewController y MPMoviePlayerController

¿Cuál es la mejor manera de reproducir un video localmente en ios6?

este es mi código

NSURL * url = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource: @ "17" OfType: @ "mov"]];

     MoviePlayer = [[MPMoviePlayerViewController alloc]
                     initWithContentURL: url];
     [self presentMoviePlayerViewControllerAnimated: MoviePlayer];
     [moviePlayer.moviePlayer play];
     [[NSNotificationCenter defaultCenter] addObserver: self selector: @ selector (moviePlayerPlaybackStateChanged :) name: MPMoviePlayerPlaybackStateDidChangeNotification object: nil];
}


-(void)moviePlayerPlaybackStateChanged:(NSNotification *)notification {


}
