I am getting the whole home upgrade today. I currently have a HR20-700 and DirecTivo. They are going to replace the DirecTivo with a new HD Receiver. (The TV isn't HD, but I know at a minimum the current HR20-700 I have has the outputs needed to connect to that TV.) The representative initially started talking about a new dish, but when I asked she realized I already had the HD dish and was all set there. I assume they will be setting up DECA in the house? Any tips or ideas of what I should expect the installer to have to do? Thanks! Also--Does anyone know if I can still watch recordings off the old DirecTivo after it is disconnected?
