title: Funky errors using MPMoviePlayerViewController
body: <p>Does anyone know what these error's mean? I get this when I click a button to play a video (download over internet on demand style).</p>
  
  <p>The problem I'm having is that my video plays with no audio. In fact the audio volume bar goes away completely on load.</p>
  
  <p>I have the feeling it has something to do with these errors heh.</p>
