I'm planning to update my D. Tv to Hi Def in the near future, and I spoke to a D.Tv rep in a Best Buy store one day and he said D.TV's Hi Def Tivo would only record 100 Hr's max of Hi Def programing ,and I understand that Hi Def has more pixels to it then standard programing, but I'm wondering if it's possible to get more then 100 hr's of Hi Def programs by either installing a larger H.D. or by adding a second H.D. ? or is there another reason besides the pixel numbers that limits the amount of Hi Def Hr's ? Thanks.
