It's a bit of software that when activated (when you need it) gives your computor a UK IP address. So you can go on sites such as BBC I Player and ITV etc and watch live TV or podcasts. Works very well. Google "expat shield" and you will find the site. I have the Hull City Player, you don't need the expat for it as you have will have paid and registered for it. Any probs let me know.
It's always made me laugh that when Brits go and live in other countries, we refer to them, almost lovingly, as ex-pats, yet anyone daring to do the same in the UK, is called an immigrant, like they're beneath contempt, taking our jobs, housing etc etc. Anyhow, few of my mates who emigrated to foreign shores swear by that expatshield!
