I just opened my 890 and read the brief setup pamphlet. Maybe I'll see the answer to this when I start the actual software install. It says that each of the four IR emitters will handle two devices. How does that work? I have six devices I'd like to control. If two of the dvd players are stacked, would I somehow place one of the emitters out in fron of those so it could transmit to both? I'm not clear on how this works.
