Hi I plan on buying an Apple TV tomorrow. I am going to get a 40gig one - is there any advantage of getting a 160gig over the 40? Also - I am buying in the USA but taking it home to the UK - apart from the adapter being american there should be no other problems right? Also the main question - what is the best way to get the Apple TV to be able to play XVID and DIVX movies? I was thinking along the lines of a shared folder on my Mac that it can stream from over the wireless network - hence why I am getting the 40gigger cause hopefully I see no need to actually store much on the thing itself? Many thanks.
