Had to leave the iMon software installed, and leave it running with RM200 mode (not MCE mode). When I switched it to MCE, I lost the ability to turn it on with the remote, and of course the "new improved" wiring makes you select remote OR pushbutton power up (but not both!), I had to rip open the system to switch the wiring just to boot up.
I left iMon installed, downloaded the proper iMon profile from Logitech, and manually edited the commands to my liking. Killed most of the morning, but it works....pretty much. At least I was able to config it to mostly mimic the 'workflow" I'm used to when I'm using the remote in DirecTV viewing.
