Hello, I live in North Dallas and am looking to buy a new Tivo 3. I will be using Time Warner Cable as my provider. Can someone tell me what is the best configuration that will allow me to use my Tivo as DVR, but also take advantage of On Demand programming. Specifically, do i need two cablecards, keep the set top box, use IR to control DVR.... I have searched several posts and it looks like it varies by region, knowledge of cust support, tech, etc.. Any help would be appreciated.
