title: mp4 file won't play in html5 video player
body: <p>I'm trying to create a html5 videoplayer on my site, but if when I try to insert the file like so:</p>
  
  <pre><code>&lt;video width="320" height="240" autoplay&gt;
    &lt;source src="gevelreclame.mp4" type="video/mp4"&gt;
    &lt;source src="gevelreclame.ogg" type="video/ogg"&gt;
  Your browser does not support the video tag.
  &lt;/video&gt;
  </code></pre>
  
  <p>it doesn't work at al, I have another video file (also mp4) which just works when implemented in the same way </p>
  
  <p><strong><em>EDIT</em></strong></p>
  
  <p>both the files are not working now, i've changed only the filenames and they just don't work anymore..</p>
