Found this thread via random googling. I'm very frustrated! My experience so far: -- I was conned into using the TWC DVR. I held out for three months, but I just bit the bullet and bought an HD Tivo. -- I called TWC and scheduled an appointment. They didn't have anything for a week. -- The day of the appointment, I unhooked the old DVR, set it aside, got the TiVo to the point where it needed to be, and waited. -- The installer actually showed up early, which was nice. He had never seen a TiVo before (or at least not an S3), and looked for the slots in the back. I managed to eventually convince him the slots were in the front. -- He did everything he could to try and bypass the firmware upgrade screen, which was just silly; if it needs an upgrade, it's going to have to go eventually, so what are you trying to accomplish? Based on my quick googling, I told him it could take up to forty minutes and he wasn't thrilled. But, after six attempts to try and bypass it somehow, he just gave in. -- It finally finished, but we didn't get any channels and it wasn't working properly. -- He read the serial number off to somebody at TWC, and they said they didn't have any record of it. They still tried to make it work, but their ultimate conclusion was that the cablecards were somehow fake (!!!). The contractor promised to come by tomorrow and get me hooked up with one that works. Without me noticing, he takes the old PVR back, meaning I have no TV at all. -- I get a phone call today from the contractors, letting me know they're out of cable cards and have no idea when they're getting more. Don't call them, they'll call me when they have more. But, if I want, they can set me up with a TWC DVR until some cablecards come in, at some undefined point in the future. GOOD TIMES.
