Hello Everybody, I currently have three HD DVR's (HR22-100, HR21-100, and a HR20-700). All three have two cables running to each, which I guess means I do not have SWM. The main unit (HR22-100) is in the LR and is connected to my router, via a switch and power line ethernet connection. It also has an AM21 off-air tuner attached. I received an offer from DTV to upgrade to Whole-House DVR for free for being a long-time loyal (5 heart) customer. What can I expect to do as far as set up? What is the optimal solution for me based on the equipment I have? What I mean is how will they set me up? Will this change require me to sign up for two more years? Should I ask for a certain set up / equipment when I call? What do I gain for installing this functionality? Will I loose any functionality? Thank you for your responses.
