アセットライブラリから映画を再生したい。カメラロールからALAssetを取得し、そのURLをMPMoviePlayerControllerに送信します。

xxxViewController *SelectVC = [[xxxViewController alloc] initWithContentURL: [[mediumAsset defaultRepresentation]url]];

- (id)initWithContentURL:(NSURL *)contentURL
{
    self = [super initWithNibName:nil bundle:nil];

    if (self)
    {
        moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:contentURL];

        [moviePlayer setShouldAutoplay:NO];
        [moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
        [moviePlayer prepareToPlay];

        [[NSNotificationCenter defaultCenter] addObserver:self 
                                                 selector:@selector(moviePlayerLoadStateChanged:) 
                                                     name:MPMoviePlayerLoadStateDidChangeNotification 
                                                   object:nil];

    }

    return self;
}

次のようなエラーメッセージ：

エラーではありません。スキームで診断を開くので、すべてのログアウトとアプリの速度が遅くなります。
