MPMoviePlayer closing fullscreen causes black view/block - ios

Question

I'm playing a video from an MPMoviePlayer (not fullscreen), when I enter fullscreen the video keeps playing and fullscreen is shown.
But when I close fullscreen again, I can only see the black background on the place the 'small' video was playing. It doesnt respond to touches or anything.
I never call stop on my player and there is no viewdiddissapear (or similar) function declared.
The movieplayer also isnt released.
I want the video to continue playing when i close fullscreen. Any thoughts?
**EDIT
It works on an iPad 1, but not on an iPad 2... strange... I need it to function on all though.
Movieplayer initialization:
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
self.moviePlayer = [[MPMoviePlayerController alloc] init];
self.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
self.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
self.moviePlayer.contentURL = fileURL;
self.moviePlayer.backgroundView.backgroundColor = [UIColor blackColor];
self.moviePlayer.shouldAutoplay = YES;
[self.moviePlayer.view setFrame:CGRectMake(1024, floorf((self.view.bounds.size.height / 2) - (318 / 2)), 425, 318)];
[self.moviePlayer prepareToPlay];

[UIView animateWithDuration:0.25

self.moviePlayer.view.position.y);
