Ok thanks Pugs. I was hoping it wouldn't be like that cos that means having a lot of network points in the HT (or where your sources are) to run back via the patch panel and out to each room. 4 sources with IR control will need 8 points! At least my points will be on an external wall so I can add them easily if required (double-brick house so internal walls are no-go after construction).
I know the media server route is cheaper, however we watch mainly FTA and Foxtel and therefore I need to be able to play from those sources which means going down this route.
