I think the address change only works with the UHF remotes, although I am able to change the address of my 2700 dish rec., but after that I can only use the 4700's remote to operate it, in which case I guess neither will help you. Has anyone with a dishplayer ever tried to change the IR address with a blue button type of remote like the one that comes with a 4700 rec.? I wonder if it allows you to do it like the 2700 does.
