title: PreventDefault alternative for IE8
body: <p><strong>Situation</strong>: Trying to modify VideoJS.com in order to work with IE8 and Youtube Chromeless API.</p>
  
  <p><strong>Problem</strong>: Progressbar dragging doesn't work (error on event.preventDefault(); 'not supported' according to debug)</p>
  
  <p><strong>Demo</strong>: <a href="http://alpha.dealertouch.mobi/video/demo.html" rel="noreferrer">http://alpha.dealertouch.mobi/video/demo.html</a></p>
  
  <p><strong>What I tried</strong>: Skip 'preventDefault' when it's IE, but if I do that I'll lose the functionality of the progressbar (drag/click forward and backward)</p>
  
  <p><strong>Question</strong>: What is the best way to solve this problem for IE8?</p>
