From my Cox Cable Internet line into my home, I plugged in the cable into my TV without a Contour TV box and I got 3 different channles, 2 are telling me about that I can't rent movies after 2025, and that last one plays a nice song that tells me that if I see this screen, call this number or try and change the channel. I'm just trying to understand why these channels appear and what RF frequency channel they are on? Any help would be appreciated 👍
