I have a THD with an Mcard which works great. One of my family members is interested in Tivo and I would just get the HD but it will be used in an area with a small cableco that does not have cablecard or HD support yet. If I were to get the HD the only channels that could be recorded are analog, correct? The THD has no way to control a digital cable box? If this is the case I would probably go with the Series2 dual tuner. Beings how the cable box can only output one stream is it worth it to get a dual tuner? Is the Series2 smart enough to record analog channels on its own tuner and digital from the cable box (at the same time)? If so then getting a DT model make sense, if not are we basically out of luck, single tuner only?
