With the recent rebooting issues on the series 2 DirecTiVo's, I started thinking about upgrading. I really didn't want to reward DirecTV for something they screwed up, but I was afraid I might have no alternative. To that end, I was hoping people on here who have them might be able to answer a few questions. Like, is it possible to buy the new unit, but activate it only in SD? Can you use legacy dishes (mind is the old round dual LNB one)? Even if I lost some of the features, I don't want to rewire the house. Also, is it ever possible to own the receiver, or am I stuck in a lease forever? Thanks.
