TiVo Bolt with tuning adapter and cable card worked since installed approx two years ago. Out of nowhere, one month ago I started missing most of the premium channels and some other channels. I've had techs out 4 times now to no avail. After the first two I followed the advice on another thread and filed a complaint with the FCC as Spectrum appeared uninterested in isolating the problem. Spectrum has changed the tuning adapter three times and the cable card once. They've changed connectors, splitters and put in a signal booster to no avail. The problem is that the channels, at random, reappear mysteriously. More often than not, however, they go and stay missing even after multiple resets of the both the Bolt and the tuning adapter. Any help would be appreciated. P.S. even though Spectrum has "elevated" the issue, the senior managers are less than responsive in resolving this issue. P.P.S. I'm also frustrated with TiVo itself as they are also uninterested in assuring these issues are not frustrating their customers. I'm actually considered dumping TiVo and going to streaming and maybe one Cable company provided DVR.
