I have Directv with 2 Directivos at my house. My parents have a super complicated Directv DVR at their house that they can't figure out how to use. I would like a huge capacity Tivo as my biggest only holds about 70 hours or less. Does anyone know if I can buy a Tivo and Tivo service from tivo and connect it to my Directv and just have Tivo service and Directv service? I know I don't want a Directv DVR because my parents' one is too complicated for me as well. Does anyone have Directv and Tivo? Will Directv let us do that?
