also depends on what directv shows as your dish type, and what the receivers are, if you have 6 dvrs and a swm dish without a swm16 they may cap you or force a tech to your house. I understand you can modify the system yourself with parts from solid signal and ebay and such to make it work with 6dvrs, but whether directv would give you a problem with that or not i dont know. Also be aware of adding receivers later, if you signup with 3 dvrs persay, then try to add 3more later, same issue may or may not apply. Would need someone from accounting or customer service to confirm. Just becareful with the legalities of this thread and what you are doing, hopefully all of these boxes are in your 5bed, 1family, 1living, 1kitchen, 3bath home lol. and not 321 main st apt 3 lmao.
