title: Error occurs in one project, not in a partially replicated second project. Related to playing multimedia
body: <p>I have two projects. In them I am trying to play video with either AVPlayer or MPMoviePlayerController.</p>
  
  <p>In the one large project that I've been developing in for a few months, I've added a new screen, a button, and code to display the video. Pressing the button displays the video. It did not work; the video displays a "loading..." for a second and then the application breaks, showing me the main method - highlighting this line:</p>
  
  <pre><code>return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppAppDelegate class]));
  </code></pre>
  
  <p>In the second project which I've just created, I mimic the new screen, button, and code exactly that I just tried adding to the first project. This project displays the video perfectly.
  The first project fails with either AVPlayer or MPMoviePlayerController, the second works fine with either.</p>
  
  <p>I've made the new screen in the first project the initial view controller, with the same failing result.</p>
  
  <p>I'm not sure what information to show you. The debug console? The frameworks I have included in one but not the other? </p>
  
  <p>I'm at wits end trying to figure this out, the slightest suggestion would mean a lot.</p>
