I am 1 year into my 2 year commitment and was able to get D* to agree to swap the SD box that I have for an SD Dvr for free. Installer will be out in a few days. Any idea what receiver I will receive? The csr was insistent that an installer must cone out to run a 2nd line to the box. I thought they could just use an SWM device, like my HD DVR has. Any thoughts? Do the SD DVRs support SWM?
