Opera and the OGG video - source location matters

I've recently been working on implementing HTML5 video on a new web site. The challenge I ran into yesterday was to get the OGG video to display on Opera 10.54. Using the following error handler, I found out what the problem was, but couldn't get any closer to a solution:

 function failed(e) {
   // video playback failed - show a message saying why
   switch (e.target.error.code) {
     case e.target.error.MEDIA_ERR_ABORTED:
       alert('You aborted the video playback.');
       break;
     case e.target.error.MEDIA_ERR_NETWORK:
       alert('A network error caused the video download to fail part-way.');
       break;
     case e.target.error.MEDIA_ERR_DECODE:
       alert('The video playback was aborted due to a corruption problem or because the video used features your browser did not support.');
       break;
     case e.target.error.MEDIA_ERR_SRC_NOT_SUPPORTED:
       alert('The video could not be loaded, either because the server or network failed or because the format is not supported.');
       break;
     default:
       alert('An unknown error occurred.');
       break;
   }
 }

Here's the video tag:

<video  id="vid-2" width="372" height="209" 
  poster="global/img/farmfresh.jpg" controls 
  onPlaying="stopSlider()" >
   <source class="source" src="global/vid/farmfresh.ogg" type='application/ogg'
      onError="failed(event)">
   <source class="source" src="global/vid/farmfresh.mov">
   <source class="source" src="global/vid/farmfresh.m4v" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
    <img src="global/img/farmfresh2.jpg" title="North Carolina Farm Fresh: Monday, April 29 at 9:30 PM"/>
</video>

The problem was the location of the OGG source tag; for Opera, the OGG video has to be the first if you have multiple source elements. Now Opera is happy as well as the other browsers.
