Ok, problem #1 is solved. Turns out I tried resetting remote to RF mode (even though I want it in IR mode) and then after going thru the menu steps to do that I could then setup the TV control. Which this time once you put in the mfg. name it starts trying codes on its' own after I told the C41 that model number wasn't in the list. Then I went back in and changed to IR mode. Works like a champ now.
Sooooo, it looks like the RC72's need to be in RF mode initially to set up the device access. Interesting.
Actually, I may try this on the Mitsubishi situation and see if I can get the menu to scan for the TV instead of keying in individual codes.
