Sadly I don't know of any non-geoblocked sources (and because it's
iPlayer I'm not sure how to rip it). Your best bets are probably
either to find a proxy and pretend to be in the UK or to email Paul
Rissen (who is around here somewhere) and see if he can get you a
copy. His email address is
firstname...@bbc.co.uk.
Yours,
Faith
