I just got two receivers from Directv and I'm trying to program my MX-700 to turn them on and off independently. They appear to listen to the same on/off signals. Is there a means to have discrete on/off codes that are different for these two boxes. As things stand now, if both units are off, and I press the ON button, both units will turn on. The opposite is true, if I press the Off button when both units are ON.

My concern is that when I have both units on, if I press the guide button on the HDDVR, I can see a button flash on the H20 also. It appears the only way for me to NOT have the other receiver listen to the commands from the remote is to physically turn the other unit off.
