Have bought Game's HD box so hopefully should get it Thursday I would think. I currently have Sky+ in the house. I am a bit confused on this Pairing issue and what I need to do. Is it simply plug in the decoder with my existing card in it turn it on and run the new install procedure ? It will be connected to the phone line btw. After this is run, then I call sky to up my subs I guess? or am I missing something more obvious?
