title: Change background-color of html5 video element
body: <p>I've got the following website:
  beta.leifsigersen.com</p>
  
  <p>There's a movie on the front page which sometimes takes a little while to load (sometimes less than a second, sometimes a few seconds). Before the movie is loaded there's black background/borders. How can I change the color of this?</p>
  
  <p>I've tried to use CSS of the video-element, but without any luck.</p>
