Code:
	
	-(void) playMovieAtURL: (NSURL*) theURL {
 
    MPMoviePlayerController* theMovie =
                [[MPMoviePlayerController alloc] initWithContentURL: theURL];
 
    theMovie.scalingMode = MPMovieScalingModeAspectFill;
    theMovie.movieControlMode = MPMovieControlModeHidden;
 
    // Register for the playback finished notification
    [[NSNotificationCenter defaultCenter]
                    addObserver: self
                       selector: @selector(myMovieFinishedCallback:)
                           name: MPMoviePlayerPlaybackDidFinishNotification
                         object: theMovie];
 
    // Movie playback is asynchronous, so this method returns immediately.
    [theMovie play];
}
 
// When the movie is done, release the controller.
-(void) myMovieFinishedCallback: (NSNotification*) aNotification
{
    MPMoviePlayerController* theMovie = [aNotification object];
 
    [[NSNotificationCenter defaultCenter]
                    removeObserver: self
                              name: MPMoviePlayerPlaybackDidFinishNotification
                            object: theMovie];
 
    // Release the movie instance created in playMovieAtURL:
    [theMovie release];
}
	In this code, which places do I fill in my url for playing the video.
