title: Force YouTube Playlist to HTML5 playback
body: <p>As I would like to be able to manipulate the z-index of an embedded Youtube playlist, I tried adding the html5 parameter, set to 1, but this seems to work for single video embedding only.</p>
  
  <p>This works:</p>
  
  <pre><code>&lt;iframe width="300" height="225" src="http://www.youtube.com/embed/VIDEO_ID?html5=1" frameborder="0"&gt;
  </code></pre>
  
  <p>But this doesn't:</p>
  
  <pre><code>&lt;iframe width="300" height="225" src="http://www.youtube.com/embed/videoseries?list=PLAYLIST_ID&amp;amp;html5=1" frameborder="0"&gt;
  </code></pre>
  
  <p>Many thanks :)</p>
