I don't know if it works in the states but here in the uk we can see the show for most of the BBC's past week here...
http://www.bbc.co.uk/iplayer/search/...ind+Programmes
the show airs at 21.00 and 21.50 Wednesdays, the shows are on line 10 mins after they finish, this is uk time so take 4-8 hrs off this for the states, or basically watch them in the evening and they will be posted..
Can any one have a go at the site and tell me if its available via american servers? and ill post any thing of interest if it happens...
