title: Video file .ogv plays locally in Firefox, but not from server
body: <p>I'm not having any problems playing this video in Chrome, Safari or Opera.  When I try to play it in Firefox, I get a grey box with no video.  Here is my code:</p>
  
  <pre><code>            &lt;video width="640" height="360" autobuffer controls preload="auto" &gt;
                &lt;source src="fracWelDay3.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'&gt;
                &lt;source src="fracWelDay3.webm" type='video/webm; codecs="vp8, vorbis"'&gt;
                &lt;source src="fracWelDay3.ogv" type='video/ogg; codecs="theora, vorbis"'&gt;
                  Your browser does not support the video tag.
            &lt;/video&gt;
  </code></pre>
  
  <p>I have also created an .htaccess file (see below) and put it in the same folder as my video files:</p>
  
  <p>AddType audio/ogg oga ogg
  AddType video/ogg ogv
  AddType video/mp4 .mp4
  AddType video/webm .webm</p>
  
  <p>The link to my file is:</p>

  <p>I would be very grateful for any help.</p>
