I just tried it with an MRF2-MTHW. (program/setup the same as the MRF2-6cl) It would not work with the old Lutron/URC codes sent from an MX-850. I tried the exact same codes with a URC/Lutron MRFA-6MLV... It worked perfectly.
As expected. I never heard there was any chance of that working until thread. Thanks for confirming it does not work.
