title: How do I resolve video.js 5.6.0 runtime error - Object doesn't support this property or method?
body: <p>I recently switched to using video.js version 5.6.0 (was previously using a 4.x version), and noticed that I now consistently get the following error using the non-minified version of video.js:</p>
  
  <p><strong>Exception was thrown at line 811, column 5 in <a href="http://vjs.zencdn.net/5.6.0/video.js" rel="nofollow">http://vjs.zencdn.net/5.6.0/video.js</a>
  0x800a01b6 - JavaScript runtime error: Object doesn't support this property or method</strong></p>
  
  <p>I haven't changed anything in my use of video.js, and the line:</p>
  
  <pre><code>&lt;script src="http://vjs.zencdn.net/5.6.0/video.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>appears immediately below the video element. The matching 5.6.0 CSS appears in a link tag in the head section.</p>
  
  <p>This is occurring under Internet Explorer 11 on Windows 8.1. The error is reported through Visual Studio 2013. </p>
  
  <p>I tried falling back to video.js version 5.4.6, but it gives the same error at the same line. I tried the minified versions of both 5.6.0 and 5.4.6, and both give the same error (at a different line/column, of course).</p>
  
  <p>I've examined the offending area, but must admit I'm not well-versed enough in JavaScript to determine what the cause of this issue is. I've commented-out all of my own JavaScript, to ensure that it's not interacting somehow with video.js, and I still get the error consistently.</p>
  
  <p>Any ideas on how to fix or work around this error?  The video.js player seems to work as expected in spite of this error, so it's not a blocking issue...just a concern.</p>
