I called Cox yesterday to add a phone (cheaper w/bundle) and replace my modem to DOCSIS 3.0. I hadn't installed tuning adapters in North Las Vegas yet. I have a Premier and Series 3 Tivo. I went in to pick up the modem and asked about tuning adapters. I told them I didn't think I was missing any channels. He looked it up and could see that I wasn't. I asked him if maybe SDV hadn't made it's way to North Las Vegas yet. He said possibly. He gave me 2 adapters, and we agreed that I probably shouldn't install them until I start missing channels.
