Excellent... I didn't know that and it's exactly what I was looking for. a work-around solution to this problem. I just checked out Harmony and they make many nice looking models. Do you have knowledge of which model(s) will work with the HR44 and handle 3 devices? The goal is One button turns 3 devices on and off.
Free remote or not, DTV should have done it right knowing that many (maybe most) customers have a surround sound 3rd device. It must have been an oversight. The code is already there in setup. The RC65 remote handled 3 devices okay on their old Genie HR-34. I don't think it's a stretch for customers to expect a 3 device remote for their latest Genie.. in my opinion. DTV is a top premium provider and I expected more from them.
Thank you for your Logitech Harmony solution. I will pursue it and get more details.
