I just turned in my TWC DVR and remote. I asked for my CableCard and tuning adapter. The old woman working the desk was a real dingbat and was like "You aren't going to get digital cable with the Tivo." Yeah, okay, whatever. I was tired and didn't feel like arguing so I was just like "Okay, that's cool. No, please keep the digital cable on my account, I want to pay for it even though I'm not getting it. Please give me a digital tuning adapter." Heh. I got the adapter (bigger than I thought, thought it was going to be a little dongle) and my CableCard. It's definitely an M-card because it says "multi-stream" on it. My bill went down $25 a month or so.
