Hi there, I was wondering if somebody can help me out with a query. I've got four av cables running into my living room which the electrician installed for Sky, as well as TV points in five other rooms. I want to get a Sky +/HD box so will I need to purchase a Loftbox Expander as well as a Loftbox? I want to be able to change the Sky channel from each of the five other rooms (with the sky box located in the living room) using a TV link. Any advice is greatly appreciated.
