Oh my.... I've having problems with my box too. When watching my DVR recordings the tv goes to a black screen for 3-5 seconds. It happens constantly. I learned last night that I could rewind and then what was missed would show. Problem is... It happens 3-5 times during an hour long show. Doesn't happen on the other 3 tvs. And I'm a new customer. Got Cox on November 29. They're coming tomorrow. They better not charge me $100 service call‼️ If so, I'll file a complaint with the a FCC because it has not worked since I went with Cox. I thought it might clear up. But NO...
