BBC Worldwide (International Site)
We're sorry but this site is not accessible from the UK as it is part of our international service and is not funded by the licence fee. It is run commercially by BBC Worldwide, a wholly-owned subsidiary of the BBC, the profits made from it go back to BBC programme-makers to help fund great new BBC programmes. You can find out more about BBC Worldwide and its digital activities at www.bbcworldwide.com
In other words... Just like everybody else in the world, you didn't pay for this site. So therefore you can't access it, but they can. D'oh!!
