Cheers Rob, I'll take a look at that link although I don't know if I can be bothered with the hassle if I'm only there 6 months.
Regarding Freeview, once the digital switchover happens in my region, I'm assuming the standard aerial on the roof will be sufficient, I'll just need a digi-box? And the standard analogue tuner in my TV (no built-in Freeview) will no longer pick up anything?
