the free/naughty way (fiddly, and slow, but the video bit is p2p so normal speed once it’s going)…
1. install tor
2. frig tor setting to use only UK exit proxies
3. install foxyproxy in firefox
4. frig foxyproxy to use tor for iplayer, etc., but no proxies for anything else
optionally, use 1 browser normally with no proxies, and a 2nd browser configured to use tor proxies. remember to do all your online banking etc. with the right one 😉
PS that also works for all the youtube vids with Sony/BMG/Warner/etc. “music” that you won’t be able to view (aka about half that get posted here).
It’s really really slow, and you’ll often need to hit refresh, but eventually it works.
