Moving a MythTV (or any media center machine for that matter) to a location other than that of the display can often be the most affordable solution to a stubborn problem. Noise. Often times, space constraints or aestetics may prevent a machine from residing near the display. Some power-users often centralize their equipment to a machine room in the basement such as this fellow has.

Another popular practice with the advent of the wall mounted flat-panel display is to hide all of the existing home theatre equipment in a nearby closet or built into a rack enclosure behind a panel thus creating a streamlined or minimalist decor. In this scenario, each piece of equipmemnt would also need to have it's respective IR signal forwarded or "repeated". An [[IR - control system|IR control system][ would be used to collect, concentrate and then deliver the signals from any remote control to the proper piece of equipment (eg.
