my TV is a bit odd when it comes to the TV tuner
It shows everything it can find, without regard for if it should be hidden or not according to the program table
So it shows me a really old Netflix loading screen on 168, a test channel with advertisements on a loop on 777, and OTA update channels for some receiver boxes in the channel list
I should post mpeg-ts stream dumps of them, tbh - for fun
especially the old Netflix loading screen
