This problem is occurs only in the simulator not on the actual device. If you want to get rid of this you need to release the MoviePlayer and allocate a new one each time you play a movie. E.g.:

- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
    // remove observer
    [[NSNotificationCenter defaultCenter] 
     removeObserver:self
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:thePlayer];

    [thePlayer release];
}

and

thePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theMovie];

[[NSNotificationCenter defaultCenter] 
     addObserver:self 
     selector:@selector(moviePlayBackDidFinish:) 
     name:MPMoviePlayerPlaybackDidFinishNotification 
     object:thePlayer];

[thePlayer play];

elsewhere.
