Advertisements I want to buy a Premiere XL. One of my current TiVo boxes is the TiVo HD XL. When I got it, I tried and tried to get Time Warner to give me an M-Card because I have to pay a rental fee for each card I get. They were totally clueless about what an M-Card was and how to request one. I ended up having to get two S-Cards instead and pay double what I would have otherwise. Now with the Series 4, I have no choice. I will not give up dual tuners to buy the Series 4. So, my question is, how can I get an M-Card from Time Warner? If anyone has any "key phrases" or part numbers or phone numbers to call, I would appreciate it.
