Hi, I have been renovating my house, and have 4 satellite cable hanging out of my wall. Currently subscribed to Sky+ and multiroom, want to upgrade to Sky HD (no multiroom for now). I need the dish moving and the both ends of the cables finishing off, also the Sky HD box will be in AV room, distributed via cat5 extenders to LCD not yet bought. Is this a standard install? Will Sky do this without ability to connect HDMI - I can set up TV so they can test via scart.
