YouTube video playback broken on iOS6 (works fine on iOS5)

Question

In my app, I have a button which, when pressed, lets you watch a youtube video (a movie trailer). Within the app, without launching safari. Below you can see a code snippet.

I have solved the problems with dharmabruce and JimmY2K. solutions, with the fact that it only works the first time a video is played, as mentioned by Dee

Here is the code(including event when a video ends):

- (void)embedYouTube:(NSString *)urlString frame:(CGRect)frame {
    videoView = [[UIWebView alloc] init];
    videoView.frame = frame;
    videoView.delegate = self;

    [videoView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]];// this format: http://www.youtube.com/embed/xxxxxx
    [self.view addSubview:videoView];

    //https://github.com/nst/iOS-Runtime-Headers/blob/master/Frameworks/MediaPlayer.framework/MPAVController.h
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playbackDidEnd:)
                                                 name:@"MPAVControllerItemPlaybackDidEndNotification"//@"MPAVControllerPlaybackStateChangedNotification"
                                               object:nil];

}


- (void)webViewDidFinishLoad:(UIWebView *)webView {
    //http://stackoverflow.com/a/12504918/860488
    [videoView stringByEvaluatingJavaScriptFromString:@"\
                                    var intervalId = setInterval(function() { \
                                        var vph5 = document.getElementById(\"video-player\");\
                                        if (vph5) {\
                                            vph5.playVideo();\
                                            clearInterval(intervalId);\
                                        } \
                                    }, 100);"];
}

- (void)playbackDidEnd:(NSNotification *)note
{
    [videoView removeFromSuperview];
    videoView.delegate = nil;
    videoView = nil;
}
