I've got a mottorolla HD cable box from comcast, and i need to know do you have to have a hd tivo?

Rodrigo Pezley: call to locate your closest comcast center. take up your previous field, they supply you an HD field. this is going to value you likely $10 extra a month yet you will obtain each and all the HD channels. in addition they'll supply you each and all the cables so which you likely won't want the hdmi cable, shop it for a dvd or blue ray participant.

Hans Sachetti: You can upgrade to a TiVo HD. You need cablecards for it to get cable programming. That would be best IMHO.You can use a Series 2 with an HD cable box though, but it will record in SD only.
