As a person who does universal remotes and home automation for a living, your post makes no sense. If I had enough devices to warrant a universal remote, I can't stick it all behind a TV. The D* remote does a TV, AVR, bluray, and D* box. I can't even put all those devices behind a TV.
For people like my parents it is easier to use the same remote at pretty much every location. So I have multiple Harmony 650s for them now. So even though in some of their locations the DirecTV remote in RF will work fine since all they need to control is the TV and C31, it still would have been nice if I could have just continued to use the Harmony 650 there and used an IR extender.
