title: HTTP subtitles in WinJS video element
body: <p>In the <a href="http://code.msdn.microsoft.com/windowsapps/Media-Playback-Sample-3bdbe7c9" rel="nofollow">HTML media playback sample</a> there's a code that demonstrates how to add subtitles to the video:</p>
  
  <pre><code>    &lt;video id="subtitleVideo" style="position: relative; z-index: auto; width: 50%;"
          src="http://ie.microsoft.com/testdrive/Videos/BehindIE9AllAroundFast/Video.mp4"
          poster="images/Win8MediaLogo.png" loop controls&gt;
          &lt;track id="scenario3entrack" src="media/sample-subtitle-en.vtt" kind="subtitles"
              srclang="en" default&gt;
      &lt;/video&gt;
  </code></pre>
  
  <p>It works fine, but when I change subtitle track src to <code>src="http://gilevskaya.com/subs.vtt"</code>, subtitles stop working.</p>
  
  <p>The file being served is the same, why doesn't it work and how to fix it?</p>
