Someone at work asked me this question, told them im not into hacking, but will post on a board were I know will get the correct answer. My co-worked signed up for direct and wanted to know, if he gets a 3rd receiver, activates it, and then installs dish at parents house and bring the 3rd reciever over, will it work? I thought maybe yes, but didnt know? Figured their might be a conflict if their reciver was on and the one at parents was on as well. I told him no, it prob would not work...thoughts??
