oh dear, the content is blocked as produced in the Uk and therefore as a UK citizen I have to pay to see it, but the rest of the world is allowed to see it - or that is what the message implied...
All three series of Black Books are available to watch free on 4oD, I believe, but then I haven't bothered checking it actually works since the box set is *jabs thumb over shoulder* in the rack over there Mind you, you'd have to find out which episode it was or watch the whole series... It is rather good, though!
It's Series 1, Episode 2 if I'm not mistaken, "The Grapes Of Wrath". Is it sad that know that off the top of my head?
British humour works for me...
