MPMoviePlayerController view disappearing when next/previous button is pressed

Question

Hi all,

I have this very strange problem. I create an MPMoviePlayerController in my view controller with the following code:

player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"vid96" ofType:@"mov"]]];
player.fullscreen = YES;
player.controlStyle = MPMovieControlStyleFullscreen;
player.view.frame = CGRectMake(0, 0, 320, 480); 
[self.view addSubview:player.view];

Now if the user taps on the next/previous buttons, the MPMoviePlayerController's view simply disappears. Is this the normal behavior of MPMoviePlayerController? Is there a way to stop this? I don't really need the next/previous buttons, so if there's a way to disable or hide them that would be ok too.

Thanks.
