I have been having pixelation and audio skips/freezes on one channel. 747 MSNBC through spectrum charter cable. It’s been going on for weeks. The spectrum cable man came out today and checked our connections and signal strength. Everything looked great. He suggested that the issue lies with the TiVo tuner. I have a cable card and tuning adapter from spectrum. I’ve repeatedly restarted the tuning adapter and TiVo but nothing fixes it. And occasionally the TiVo error message V53 pops up stating poor signal quality. It’s just with this channel. Does anyone have an troubleshooting tips to fix this?
