UK OnDemand Websites

I've been missing Hulu.com ever since I left the US. Finally found a decent set of alternatives - although some sort of aggregation would be a plus:

http://www.bbc.co.uk/iplayer/
http://www.channel4.com/programmes/4od
http://demand.five.tv/WatchNow.aspx
http://www.itv.com/itvplayer/
http://www.adultswim.co.uk/video/
http://www.mtv.co.uk/videos

These probably all just work in the UK, but if you're floating on this island not a bad set of choices...
