I am not on Catalina, still on Mojave, and I too am experiencing slowness with 1.18.1.1973. If I have three streams going, watching live TV is a no no. Yet I can fire up the HDHOMERUN Mac app and watch as much live tv as I wish. So it’s not a network issue.
This is what I get when I do anything involving Live TV or DVR. I have attached my logs. I am running Version 1.3.1.916-1cb2c34d of the Plex app for Mac and 1.18.1.1973 for the server.
