My father in law bought an old Gen 6 RCA receiver from a friend of his that used to have D*. My father in law wants to put this receiver in his grandkids playroom, but when he phoned D* the csr told him that the card (P4 still sealed in factory plastic and never used) would not work with that old of a receiver, so D* wants him to buy a new card for $75. I have never heard of this. I told him that the card is still sealed so it should work and to hold off till I could find out for him.
