//***************************************
//***************************************

{

	NSString *path;
	NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
	path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"MyVideos"];
	path = [path stringByAppendingPathComponent:@"MyMovieFile.MOV";

	if ([[NSFileManager defaultManager] fileExistsAtPath:path])		//Does file exist?
	{
		moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path]];

		[[NSNotificationCenter defaultCenter] addObserver:self
												 selector:@selector(moviePlaybackComplete:)
													 name:MPMoviePlayerPlaybackDidFinishNotification
												   object:moviePlayerController];  

		[self.view addSubview:moviePlayerController.view];

MPMoviePlayerController Stopped Working in iOS5?

We came across an issue which appeared with iOS 5 playback of movie files to which the path had been stored as a string. In iOS 4 this worked fine:

moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:path]];

But not in iOS 5! Instead the movie window opened and immediately closed again. This was the solution:

moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path]];
