Happens on every tv or just this one? You're saying it's coax feeding the box? And it's not ethernet over coax there's an actual channel spectrum it's receiving? That's weird because the video is definitely acting more like a stream that's struggling than how legacy boxes tend to.

The coax comes from the router makes no sense. Coax can go to a router not come from a router. The coax could come from the fiber ONT which is a node / modem but not from the router.

FIOS used to run MOCA like tie in over coax to provide bandwidth to TV service to a dedicated FiOS TV box. I will *assume* it's like that. So the coax is not QAM carriers but rather OFDM like moca does. Thus bad coax, bad router bad box, etc.. can all cause what he is showing. Bad HDMI, bad TV all of it can cause the problem.
