I downloaded about 10 existing MX-700 User files at remotecentral.com:

Whether .mxd or .mxf file, when I open them up why don't these guys have cable box power ON/off button?...or my TV, Pioneer 533HD5, i imported 5 different guys files, no power on/off buttons...These guys have to be turning on their cable box in a macro, but where???

How accurate is URC IR database? is it 97% range or 57% ballpark?

lie I said in earleir post, both the cable box model and TV model are in the mx-700 editor, but go to the device pages, no power on/off?

what's the deal?

I guess like Gonk says, you can learn anything the database falls short on.

Thanks Vince
