Just a thought,
Might sound silly but can you not register in the UK with
BBC - About the BBC - BBC iPlayer
ITV Catch Up
channel4.com - watch online
home | five.tv
As you have a dedicated UK IP to register with at home can you not simply use this service online?
There are similar for other channels and if you have a sky account you can watch Sky Movies etc online
