title: "Movie Format Not Supported" on iPhone with YouTube player in a WebView
body: <p>I'm using a UIWebView on iPhone to play YouTube videos. This is working fine most of the time, but not all.</p>
  
  <p>Under some circumstances, apparently related to network connection issues, the error "This movie format is not supported." is shown. This same error can be seen in both Safari and the YouTube player under the same circumstances.</p>
  
  <p>Unfortunately it has been seen by Apple during the AppStore testing so they've rejected the app.</p>
  
  <p>Can anyone suggest methods for detecting and handling the error more appropriately or alternatively any other video hosting system where we could get a similar experience without the player issue?</p>
  
  <p>Thanks for your help,</p>
  
  <p>Larry</p>
