I installed JRiver Media Center 26.0.102 64-bit for Apple macOS 10.15.6 64-bit "Catalina" and I turned on the media network and I enabled generic DLNA. When I go through the television setup wizard, it shows nothing under network tuners. However, when I connect to my mid-2017 AVA Direct gaming desktop PC running Ubuntu 20.04.0 64-bit LTS GNU/Linux and I already opened JRiver Media Center 26.0.94 64-bit and I access my JRiver media server in my apartment, I can stream over the air television just fine. I want to be able to connect to my empty main library and find my Silicondust HDHomeRun Connect Quatro so I can watch over the air television and log into my Perc Data to download my electronic programming guide every hour as I have done so on my three GNU/Linux powered PCs in my apartment. Why is it that JRiver Media Center 26.0.102 64-bit for Apple macOS does not show any network tuners?
