I have read the other threads and still don't understand why an S3 box needs a cable card. As I understand it, I have to rent Charter's digital cable box, purchase a Tivo Hi Def DVR box and rent the cable cards so the Tivo will work? All this while paying monthly for the Charter HD package. Oh and the monthly Tivo service. My current Scientific Atlanta 8000 HD DVR box doesn't use cable cards and I get all their HD channels. Can you tell I am having trouble keeping up with the hardware? It just seems like it will cost me a ton of money just to watch and record HD TV with an easier interface. And I certainly don't understand how many people can afford mutiple boxes and services. Am I the only poor person out here? When will the TV technology be easier? Wide screen and high definition content only!
