I did find the TIVO Premier version 4 works with antenna. It required connecting the antenna, pulling out the cable card and running guided set up. It would not do a channel search to discover the antenna channels without removing the cable card and starting over. Then it asks if you want to set up for antenna only, cable and antenna, or cable only. I went with cable and antenna and at some point it had me reinsert the cable card. I have all the COX channels and 40 or so antenna channels now.

So...like everyone else in this and the other thread, now I'm shopping to find some of the wife's can't miss shows on a streaming service. Five are Discovery, HGTV, TCM, Ion and AMC. Have not found Discovery or Ion, but have found most of the others in various services, just not the same one. I don't think I'm going to get there without staying with COX or maybe Direct TV. I started to sign up for Hulu live TV package last night but there are hundreds of posts on their forum with people having buffering issues with it.
