The TiVo Premiere DVR replaces your cable box
The TiVo Premiere DVR replaces your cable box, but you still keep your cable service. It plugs directly into your cable service to deliver your cable TV programming.
to answer the incredibly basic/stupid questions I had about whether you can get specific Tivo content if you're not subscribed to that content on Comcast. "Keeping my
service" is one thing; having to know that I also have to subscribe to, e.g., Comedy Central on Comcast before being able to get it via Tivo is another.
But I'll keep clicking and reading more and appreciate the follow-up. And clearly I have so little concept of how this all works that maybe I'm a pretty hopeless case
