I have been using this Firefox Add-on to watch BBC iplayer, ITV player and 4OD outside the UK. It couldn't be easier to use, just set country to GB, click it on and once the program starts switch it off.
Some of the reviews say they had to switch it on and off a few times to get a fast enough proxy but I have had no problems.
I also used it to access Hulu (US) and it can be changed to use proxies from France, Italy, Germany etc if that's of use to anyone.
Apologies if this has been posted on here before
