I have Time Warner digital with 2 HD cable/DVR boxes. I hate paying a monthly fee for these. I also have a third TV with no box which only gets the basic 70 or 80 channels. Would TiVo record ALL channels (including those over 100)? If not, would it do so for satellite? I'm looking for a solution that involves a hardware purchase and allows complete DVR-style service (including HD) without rental/DVR fees, if that's possible.
To clarify, I'm under the impression that the cable box itself is what "unlocks" certain premium programming. So, say I buy a TiVo and subscribe, which basically gives me an on-screen program guide and recording capability. Let's say I then call TWC and add some premium channels to my account. Will the TiVo box be able to play those channels??
On a related note, I'm able to find my cable box (which is a hi-def DVR) on eBay. If I simply buy it and hook it up, is it going to work? What can I expect if I do that?
