I'm in Canada as well, and can't view the video either. I'm glad that others are making the same observation, because even last night I spent too long a time trying to get Comedy Central clips to work on my home computer (at school, the browser just locks up going to the Daily Show homepage). After installing Firefox and every up-to-date pluggin I could think of (all on a new Vista machine) they still wouldn't work - so I came to the same conclusion, and knew it had to be a regional blocker.

All this wouldn't be so bad if the site Canadians are redirected to would work - the viewer is so messed up that clips can't be selected properly, and play-back is terribly slow. It's a shame I had to give up trying to watch anything, because God knows I really want to. This is incredibly frustrating.
