There is the PAL/NTSC issue, I know that my DVD player does the conversion for the TV (multi region player) but I'm pretty sure that my TV can handle both signals, you could probably see from the manual whether yours can.
One of the bigger problems is the electricity supply, over in the US it's 110V at 60 Hz, but the UK 220V at 60Hz. SO unless you're prepared to buy a transformer with some meat in it, I'm not convinced it would last long before something died, if it worked at all.
