title: HTML5 track captions not showing
body: <p>I am trying to make the simplest html5 video player in the world:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;meta charset="utf-8"&gt;
          &lt;title&gt;ST Media Player&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;video id="player" src="http://video-js.zencoder.com/oceans-clip.mp4" controls&gt;
              &lt;track kind="captions" src="_tracks/test.vtt" default&gt;
          &lt;/video&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Done!</p>
  
  <p>Now why does the player recognize that there is captions, but doesnt show them? I have tried different video's and subtitle files now. </p>
