As others have mentioned, the voltage shouldn't be a problem.
We brought 2 x TVs with us, one had built-in freeview, the other didn't. It's highly unlikely that anything Freeview you bring will work, so ditch any boxes or PVRs you have. If your TVs have a multi-system analogue tuner then you'll be fine, if not then I'd suggest a digibox - there's far more choice on digital anyway.
Anone other issue that you'll come across with TVs is scart, or the lack of it - they don't really use it over here so either factor this into your decision (to keep or not to keep) or simply get hold of some s-video+audio to scart cables while you're still there - try www.tvcables.co.uk .
If your DVD player isn't multiregion, let me know and I'll see if I can find a hack for it ;-) Australia is PAL region 4, by the way. For analogue they use PAL B/G, same as a lot of Europe (except France).
thanks for that justin,its all great info
See you soon! ;-)
