Seriously, this is 2012! You would think by now that the usb ports on the back of all our tvs, blu-ray players, game consoles cable boxes and ect would allow us to interconnect all the the devices so that only one IR reciever is used for everything.
They do have this now. The new devices are all HDMI+ethernet, and you can set it up so that one remote rules them all, no problem. Our blu-ray, TV and receiver all "talk" to each other, and I can use the TV remote to control them all, no programming or IR code ---That which is odiferous and causeth plants to grow---. Cable boxes is what screw things up, but since we are cable-free, we don't have that problem anymore. Its to the point where we don't even use the logitech remote we have.
I love the logitech's have had 2 different models, and gave one to the inlaws, I've never had a problem with them at all. I always tell my friends, "get one of these, they are idiot proof" however, it seems that once again, this forum has proved me wrong.
