We have our Nexstar 2023 HD domestic satellite receiver, there is a red dot on the remote control, it says to insert a USB for monitoring recording, I plugged it in, it gave a warning or something, the TV has 72 screens, there are HD or non-HD channels, I think one of the 2 is doing that job, the flash seemed to stay in my hand, I bought it to operate it on the satellite receiver. Or I will go with the box and have it adjusted to the satellite receiver, I will go with the remote control and maybe I need to update the satellite from the internet, it is a 2 cm2 thing that connects to wifi, but I think the satellite will solve it, it may very well need an update from the internet.
