Explain that one a bit better, are u wanting the kids to watch sky, if so u'll need multiroom so u may as well contact sky, if u want to slave a cable off the back of your box then they can only watch the same channel as what's on the main box. This is unless u have sum dodgy sky box
Been sent another Sky HD box, wanting a cable running from dish into bedroom. LNB will want changing I think on dish to run another sky box off dish.
