I have just bought a second-hand sky digital box (Panasonic DSB30).

What I would like to be able to do is this - subscribe to a Sky package, at some point buy a second box for upstairs (would have to split cable somehow, how ?), and then use the one sky digital viewing card in both boxes depending on what room i am in.

Is this possible ? I know I can pay an extra £12 to have the same package on both boxes with 2 viewing cards but I dont want to pay the extra when only one box will be viewed at one time.

This was the ONLY thing I liked about ITVDigital - the fact the cards could be swapped between boxes (oh and apart from ITV2 being FTA channel !)
