Cant remember which one it is. The old school one for the HR20. I have it programmed for the tv (58" Panasonic plasma) and the box. It'll turn both on and off like it should and even control the volume so I think I have the right code. But for some reason, it wont change tv inputs. Not enough of a problem to warrant spending a ton on a Harmony so I was just wondering if this was a common problem.
