title: MediaElement plays video, but no video shows
body: <p>I can open a video, play it and get position and set position, but nothing shows up in the video window on one pc. The code works fine a on a couple of PCs, but doesn't work on another. Does any one know or can refer me to what files I need to properly run MediaElement on XP pro.</p>
  
  <p>Thanks,
