Good eye @sa2000, it is nice to have an employee who has the answers so quickly. I did have just such a setup but did not realize that starting plex as a service when the computer started up would cause such an issue. A nice update for the Plex server, that I have used in the past is that IF plex media server.exe is running, do not start a 2nd instance.
I have made updates to my system and have again repaired my plex db.
Now, even though I forgot to update the thread, it’d be nice if we could get the issue of the NVidia Shield losing the TV device fixed: Recording failed. Please check your tuner or antenna - #36 by dzeff
That would resolve most of my issues.
