Social Theme Intro Video not workin

Hi, I'm trying to use a youtube video in the mentioned theme, but nothing happens when I enter the link. I've tried:
http://www.youtube.com/watch?v=fEIX6NMRFgM&feature=youtu.be
and
http://youtu.be/fEIX6NMRFgM

But neither gives any result. What am I doing wrong?

Thanks for any helpful advice.
