I have a Directv account in Arizona and just had one of my old boxes which still works replaced with a new one. Since they didn't want the old one back, I still have it and card. Question...can I take the old one to RP and use it there or will Directv detect that and give me grief? If so, any suggestions would be appreciated. I already have a dish installed in RP and have been taking a receiver down which gets to be a bit of a hassle. Thanks!
