A user in the TiVo Community forum stated that upon contacting Time Warner the company said that you cannot use a TiVo with Time Warner Cable.You might remember back when the Series 3 was launched how difficult cable companies were trying to make it so that for users to use a TiVo Series 3 with their service. In fact Time Warner first of all refused outright to use the Series 3 TiVo with their service before later changing its mind.
If your Cable Company says they don't support TiVo then you might like to remind them that it is an FCC regulation to provide CableCards for TiVo.
If anyone else has been having these problems with Cable companies please let us know.

1. It's been quite some time since CableCARDS have been available, but service agents and cable companies still don't understand. When I scheduled, I had them repeat back to me that I needed 2 cards, yet the installer showed up with none, and proceeded to tell me that Knology didn't carry cards that would work with TiVo! I told him to try anyway, but he had to leave to pick one up, assuming that I wouldn't want the second tuner to be active. My wife's comment: "Look at this system. Do you really think he'd spend this much money to be satisfied with only half of the TiVo?" Had to leave to get the second card. Since then, they've turned off my service twice, not understanding that I just got rid of my box, not my service.
