I have had PC programmable remotes for 11 years. Have done JP1 remotes and have an MX850 which I had hoped to reprogram with three new Home Theater components. I can guarantee you that my macros are superb for my home theater. Never read one page of the manual for the MX850, messed with the software before I purchased years ago.

Now what?

PM if you have new software. I have hosted Remote Control programs before and can certainly do it again.
