After not using my tsu3000 for about a year and a half I am starting to get programming it again since I have all new equipment, and my wife wants any easy to operate remote. However previously maybe almost 2 years ago when I first programmed macros, they were not always reliable, I am away on business so I cannot test it right now, but I am just wondering how reliable are the macros since the firmware, at most I would only use a macro with two codes, anything more and if something goes wrong, my wife will have no idea what to do.
