It is still working, thank you! Except for a (relatively) minor problem with thumbnail generation with individual TV episodes. But the server is working with the clients just fine. I’m so happy.
See the new post for details about the thumbnail issue. I thought about continuing it here, but it is a different problem.
But thanks again! I now can use one app for everything. Plex client is working for movies, TV shows, Live TV with my tuner card… its glorious! The episode thumbnail issue is an annoyance, but it is working!
