I still use my series 3 HD and receive OTA HD locals. I can't get guide data by cablecard since I don't pay for a cablecard so I find the shows I want on the analog guide data and setup a manual recording on the OTA QAM stations. Does the Roamio have QAM setup also or is my series 3 the last models with it? I also read a vague description somewhere of people able to buy a cablecard on ebay and be able to sync the OTA QAM guide data with the analog on the tivo so I wouldn't have to do it manually anymore. Any truth to that?
