Help needed - why does Sky+ need two satellite inputs?
Could someone tell me why Sky+ needs two satellite inputs to record one channel while watching another? I mean, I can understand that there needs to be two tuners, but why two inputs? Can't the box just take one input and double it? And would it be possible to just get a signal doubler and plug it in between the satellite signal and the Sky+ box, so that the one cable carrying the signal is doubled and fed into both the inputs? Would this work? Any help would be much appreciated.
