MPMoviePlayerController Problems

[smithms]

I have a navigation based app with a table view and detail view. The detail view contains a UIButton which plays a move. The movie is selected from a key value located in a plist.

This all seems to work fine until I play any given movie more than once. The first run of a movie works fine. The second time around the movie begins to flicker erratically in the simulator and if a movie is played repeatedly back to back the app sometimes freezes or crashes altogether.

Does this sound like a memory issue or is there something else I am missing?

Thank you in advance for your time.

-(IBAction)playMovieButtonPressed:(id)sender
{
			
	// Path to the movie
	NSString *videoSelection = [dvdData valueForKey:@"video"];
	 
	NSString *path = [[NSBundle mainBundle] pathForResource:videoSelection ofType:@"m4v"]; 
	
	NSLog(path);
	
	movieURL = [NSURL fileURLWithPath:path];
	
	
	
	// Setup the player
	moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
	
	moviePlayer.movieControlMode = MPMovieControlModeDefault;
	moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
	
	

	
	// Wire up the movieFinishedCallback method
	[[NSNotificationCenter defaultCenter] addObserver:self 
				 selector:@selector(movieFinishedCallback:) 
				 name: MPMoviePlayerPlaybackDidFinishNotification 
							   object:moviePlayer]; 
	
	
	// Start the movie  
	[moviePlayer play];
		
		
	NSArray *windows = [[UIApplication sharedApplication] windows];
	if ([windows count] > 1)
	{
		// Locate the movie player window
		UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow];
		// Add our overlay view to the movie player's subviews so it is 
		// displayed above it.
		[moviePlayerWindow addSubview:overlay];
			
	}
	
	
}


// Callback should be in controller as the playVideo code
-(void)movieFinishedCallback:
(NSNotification*)aNotification 
{
	MPMoviePlayerController* theMovie = [aNotification object]; 
	[[NSNotificationCenter defaultCenter] removeObserver:self name: MPMoviePlayerPlaybackDidFinishNotification object:theMovie]; 
	
	// Release the movie instance
	[theMovie stop];
	[theMovie autorelease]; 
	NSLog(@"The movie has finished!");
}



- (void)dealloc {
	
	[overlay release];
	[movieURL release];
	
    [super dealloc];
}
