So far, so good...
Window was from 8am to 11am, and of course he showed up at 10:45am. Was hoping to be the first stop of the day, but I guess it wasn't meant to be.
Of course, inserting the CableCARD took no time. We wrote down the "tm" and "host" numbers we needed to relay to the guys in ATS (advanced tech servcies). No issues.
The longest part of the install was the installer going out to my terminator box on the side of my house, and up to the top of the pole, to inspect the signal strength and cabling. They're mandating new terminators on the cabling, so he stripped and re-terminated all of my wiring external to the house. That took about 15-20 minutes.
Once that was complete, the TiVo had already upgraded the CableCARD firmware and downloaded the channel guide. The call to ATS wasn't 100% smooth, with a small glitch on their end, but after a minute or two things were resolved. TiVo was able to tune a few premium channels that I subscribe to.
Bottom line : 45 minutes from start to stop. So far, so good... FAR better than last time's go-around.
