I have a dish 625 dvr and a hd 811 box they are both in the same room I am looking to upgrade to the 211/411 since the 211/411 is an Infrared Box and the TV1 of the 625 is IR is it going to cause a problem being that I have them right on top of each other. I guess my question is is the one going to control the other and if so is there a way around this. I called Dish and they weren't really understanding what I was asking.
