We just changed our older Sony and Hughes receivers for one HD DVR (HR24-200) and one standard receiver (D12-700 refurbished). The standard receiver is the one we're having a problem with - when we turn the receiver off the sound will not turn off. Has anyone else had a problem like this? Also, we carry the standard receiver with us when we take our RV. Our older Hughes was very easy to get a signal, but in doing a trial run with our RV here at home, we can't get any kind of signal on the Directv receiver. We were told this receiver would work with the dish and LNB we have been using for years. Can't seem to get any help from Directv - just transfer from dept to dept. Any ideas?
