title: Changing video source in a web player
body: <p>I'm trying to make a web player and it is supposed to change the video source by the click of a button, but it does not work, I've tried everything.</p>
  
  <pre><code>myVideo.src = "http://www8.cs.umu.se/kursmaterial/html5/mediafiler/WaterBalloon2.mp4";
  </code></pre>
  
  <p>This part is supposed to have 2 video sources, 1 for mp4 and 1 for ogv, which I can't seem to figure out how to do.</p>
