I have a Tivo Bolt and I got the cable card and tuning adapter. Cable card is paired and everything is up properly EXCEPT the tuning adapter. I have been on the phone off and on for quite a while with Charter about it. I kept losing the call. At one point I had it hooked up and ran the test for channels and it stating no channels. I was finally told to take it back and get another. I will do that tomorrow. Hopefully it will work then. I find it odd that it stated that it was hooked up and then it stated that there was a problem and it was not connected to the TiVo. Any suggestions when I get the replacement? Maybe my coaxial cable was not great. Who knows? I got some channels and then I would go to the other channels and I would get the error message! Ugh!! Stressing me out!
