Hi, I am about to get Directv for my house but I have a question. A friend of mine has Directv Business. He had cancelled 3 Receivers and Directv has never asked for them back as they were purchased through SS, so he says he owns them. He has offered to give them to me. My question is am I allowed to use them and if yes is all that is needed is a new card? The recievers are all HD-DVRS; 1 is an HR24 and the other 2 are HR23. Thanks.
