Advertisements I got a letter from Charter that said I need a tuning adapter for both of my HD Tivos. I made the appointment and the Charter technician arrived on Saturday. I had printed off the "How to install a Tuning Adapter for switched digital video" from Tivo's web site. When the Charter technician arrived I asked him if he had installed tuning adapters for Tivo before and he said that he had so I figured he didn't need the installation instructions. I think he installed the adapters wrong. He disconnected the coax cable from my Tivo. He then connected a splitter to the coax cable. He then connected one coax from the splitter to my Tivo and the other to the Tuning Adapter. He connected the USB cable to my Tivo and the TA. I don't think that is correct. He should have ran the coax to the TA and then another coax from the TA to the Tivo. Isn't that the correct way to do it?
