I have a Tivo Bolt with Gen 1 Mini. Passive Drop Amp with built in MoCA in the attic. Tivo Authorized PoE filter at tuning adapter. Tivo bridge. I believe everything is setup properly. The signal at the Bolt is beautiful. No chop, drops or anything. Yet at the Mini, it's not terrible but the signal gets slight interruptions of lines and flashes of distortion in long horizontal blocks about every 3 seconds. It only occur on locals and lower channels, 4 - 28 and the HD higher channel alternatives. The rest of the channels are beautiful like the Bolt. I tried removing the splitter at the tuning adapter and using a direct connection (I know a splitter is recommended.) Didn't help, although it didn't make it worse. I switched out the PoE filter. Same result. Rebooted both devices several times. No change. Spectrum came out and did a signal test. It's strong. They are at a loss of what it could be. I'm at a loss too at this point. Any ideas would be greatly appreciated.
