I am looking for a way to control several HDTVs in several different rooms via a HDMI matrix switcher. This is the setup that I have imagined: The switcher would have several devices (DVR, Blu-Ray, etc.) attached to it via HDMI, and then 3 or 4 HDMI output cables going to the several TVs. The problem is, how would I control it? I have thought of buying a universal IR remote, then having an IR extender by each TV going to the AV closet, and then program the IR codes or whatever for each device (including the matrix, DVR, Blu-Ray) into the remote. Is this possible? I am most concerned about the control of the devices using the IR remote.
