Just downloading the 6th episode of Ricky Gervais' Extras... watched the first five Wednesday... Absolutely brilliant! One of the funniest comedians out there at the moment IMO though I really didn't enjoy The Office in the slightest.
Politics and Animals are well worth a watch with guaranteed belly laughs, (so long as you aren't easily offended because he has a go and everyone/thing he can think of).
Through a newsgroup > alt.binaries.multimedia.comedy.british - which I access through www.giganews.com
Plenty of people out there that record shows straight from their tv (card) and post them often within hours of the show finishing. Great quality most of the time too... these are perfect even at full-screen
