About a year ago, I changed my Service Address so I could get the Distant Networks. I want to purchase a LCD TV for my upstairs living room. Right now, I have a regular DirecTV receiver and a Tivo. I obviously would like to get a HD receiver and DVR for the new LCD TV. My question is this. Wont I have to change my Service Address again before I order the equipment thru DirecTV so the installer wont say anything? Then I'm assuming perhaps after a month or so I can call and change my Service Address back to where I have it now?
