I think you're lucky Johnny if thats the case. They won't give us multiroom because we don't have a phone line in the house and a mate of mine had multiroom with 3 boxes, wasn't using the house phone so they disconnected it. Sky rang a week later and said to reconnect or they'd start charging full price for each box.
Just thinking that we have our box and dish set up so if my parents got multiroom for €15 and I took the card and plugged it into my box, would it work that way and I could leave the other new box plugged in at their house? Or are the cards programmed to the boxes now?
