Advertisements We recently moved from DirecTV (HR10-250 Tivo Box) to Comcast. My family wants to kill me as they all miss the Tivo. I like on demand and all the HD content, but I can't stand the Comcast HD DVR either. If I get a Tivo HD, I know I'll lose on demand, but will I still have to use the same awful Comcast channel guide or does the cable card/Tivo combo offer a different interface to the channel guide? Also we're contemplating switching back to DirecTV. Has anyone used bot the Cpmcast HD DVR and the "newer" Tivo H20/21? How do those compare? Thanks.
