I have a Time Warner subscription and a cable DVR box downstairs. Upstairs I am currently just using the coaxial cable and recieve 69 analog and 14 digital channels. I would like to buy an older Tivo with cablecard support and use it without a Tivo subscription to be able to pick up the same HD channels as my cable DVR box that I have downstairs. Everything that I have been told so far is that this is possible. So, can I buy a used Tivo without a subscription such as the TiVo TCD652160 HD Digital Video Recorder for $70 from amazon? .. and get a cablecard from time warner for $2.00 a month and recieve the same HD channels as my cable box downstairs without a Tivo subscription or a cable box upstairs?
