I put in 24 components.. Used IR database to put commands on the hard buttons and the ones I typed for the screen I used the learn function. I don't really care for macro's because for ex: if I just want to watch tv I don't always want 4 other things turning on. I also use a few triggers for things I do want to turn on.
I have 4 TV's and an OTA antenna with no cable. I want to put in 7 channel numbers so they work with the channel logos.
