Hi all, I tried searching for this and could not find an answer maybe someone here can help! I have a few C51-100 mini receivers left over from my old DTV. I no longer use the service and DTV does not want them back. My mother has DTV and she has an old SD receiver (along with one HD receiver). My question is, can I swap out her old SD receiver and replace it with one of the C51-100s? Or does that little guy need to be paired with a Genie? Thanks in advance!
