how to play video on external ouput using MPMoviePlayerController??

Question

Hello All,

I want to play video on iPad + external output (both at same time as youtube does). Currently I am using MPMoviePlayerController class to play videos, but when I create two instances of it only one works. Here is the code -

    MPMoviePlayerController * playerViewController  =  [[MPMoviePlayerController alloc] initWithContentURL:url];

    MPMoviePlayerController * playerViewControllerES  =  [[MPMoviePlayerController alloc] initWithContentURL:url];

/* adding movie to external screen */
    if ([[UIScreen screens] count] > 1) {

        externalScreen = [[[UIScreen screens] objectAtIndex:1] retain];

        screenModes = [externalScreen.availableModes retain];


        int screenResCounter = -1;

        for (UIScreenMode *mode in screenModes) {
            screenResCounter++;
            CGSize modeScreenSize = mode.size;
            [playerViewControllerES.view setFrame:CGRectMake(-1.0f, -20.0f, modeScreenSize.width, modeScreenSize.height)];
        }


        UIScreenMode *desiredMode = [screenModes objectAtIndex:screenResCounter];
        //[self log:[NSString stringWithFormat:@"Setting mode: %@", desiredMode]];
        externalScreen.currentMode = desiredMode;

        //[self log:@"Assigning externalWindow to externalScreen."];
        externalWindow.screen = externalScreen;

        [screenModes release];
        [externalScreen release];

        CGRect rect = CGRectZero;
        rect.size = desiredMode.size;
        externalWindow.frame = rect;
        externalWindow.clipsToBounds = YES;

        [external_screen_view addSubview:playerViewControllerES.view];
        externalWindow.hidden = NO;
        [externalWindow makeKeyAndVisible];



    }

/* adding movie to iPad screen */

    if ([currentOrientation isEqualToString:@"lt"])
        [playerViewController.view setFrame:CGRectMake(-1.0f, -20.0f, 1025.0f, 788.0f)];
    else 
        [playerViewController.view setFrame:CGRectMake(-1.0f, -20.0f, 769.0f, 1044.0f)];

    [self.view addSubview:playerViewControllerES.view];





    //---play movie---

    [playerViewController play];    
    [playerViewControllerES play];

I think the problem with multiple instances of the MPMoviePlayerController.

Please help!

Thanks
