I've bought a new house and I'm about to start refurbishing it. Electrics seem okay but it needs central heating installed and complete re-decoration. I'm not trying to build a home cinema, but I'd like to be smart about how I wire the AV. In my current house I had the foresight to install Cat5, which proved to be a great idea. I have lots of computer and AV equipment scattered around the house. Living room, kids room, office etc. This time around I'm thinking about centralising the AV. e.g. I have devices running XBMC which I'd prefer to house under the stairs then under the telly. I'm also thinking that if I centralise it and put HDMI sockets around the house, then I'll be able to send video to wherever I want it. I don't know much about the limitations about sending HDMI, USB and infra-red repeaters over distance. Can someone give me some advice please?
