I called to activate an old 311 receiver that I bought from a satellite dealer a few years ago-no balance, receiver and card are CLEAN. They said that, with my setup, they can NOT activate it-I have a 522 dvr and 722 dvr with the HD type dish. Something about no longer are the MPEG-2 receivers being any good. They also said they are getting rid of the 522 dvrs. I guess the 311 receivers are paperweights now.
