My AV equipment is located at the opposite end of the theater from the entrance. Should I be placing the GraphicEye at the entrance so I can turn on the lights as I enter, or should it be located with the AV equipment (out of sight) and control the lighting only with the emote?

I have a question about the installation of an IR Repeater Receiver Eye. Can I mount this in the back of the entertainment center cabinet, near the very top and still get the remote control signals to via the wall? I from past experience that remote control signals can bounce off the walls...
