Every AFN channel have this problem. To lose video I have to switch from a working afn channel to another. To make the video come back I have to go to whatever different from an AFN channel (recording, fta or encrypted channel) then go back to the AFN channel.
Unfortunately I cannot say if it is an update issue since I'm using oscam-emu for the first time (only plain oscam till now).

I am 99% sure this is a driver problem. Post in the openatv forum or the github repository and ask them to the ask a fix from the manufacturer.
Thank you for your efforts Nautilus7 :thumbup::shake1:
