There are similar (if not same ) questions out there.
youtube donot give direct access to video (which MPMoviePlayerViewController expects). hence it cant play the youtube videos directly (using initWithContentURL).

The only method is to play Youtube videos in your app is through UIWebView. see How to Play Youtube video in webview in iphone? to get better idea on how to.
