I acquired the original DirecTiVo and associated dish back in 2004. I bought two receiver boxes, both of which are connected to non-HD tube televisions. Last year one of the DirecTiVo boxes stopped working and I replaced it for free with one of DirecTv's generic DVRs. I don't much like it. My other DirecTiVo has started giving me trouble. Like the first one it spontaneously reboots itself on occasion. My question is this: Can I acquire the new DirecTiVo box without replacing my satellite dish? I don't need to use the HD functionality. I just want to get the same content I currently receive but be able to use the TiVo interface.
