The show is on in the UK tonight; from what I remember previously, the videos are opened up for the UK from that point. Not the worst thing in the world, restricting YouTube videos until they've had a chance to show the full episode in said country. It's not like this is just a clip - it's a whole segment of the show.
It just feels like what footballer fan (soccer you,yanks) would feel if they had to wait over 24 hours to watch a world cup match .... most would just find another way to watch it.
