Any ideas on how to control 3 identicle cable boxes ( motorolla high def) that feed one room with three displays? I'm using an MX 850, two LG lcd's and a sim2 c3x projector and would like to be able to watch different things on each display at the same time and have independat control of each box as well. Did I screw myself or am i missing something obvious that i hadn't thought of? I also currently have only one IR sensor in the room above the screen. Any input is much appreciated thanks
