you can just plug the box in and watch what you want to watch according to the phone call i made about an hour ago

if you want to add the hd to the package then you have to pay an extra £10 a month

if you want mulit room you need to pay an extra £10 a month

BUT

if you have an old card then you "should" be able to recive all the free to air channels, although this hasn't been the case with me

when the box arrives i shall verify all these "claims" made by sky
