Server Version#: 1.32.3.7089
Player Version#: 1.70.2.3845-31e96af6
This has persisted for a while across multiple versions of “Plex for Windows” and “Plex for Mac”.
When using either, if one enters the settings, and checks the LiveTV menu for a given server, then they will not see what tuners are in use.
This behavior works properly when using Plex Web - e.g.: via plex.tv, or when connecting to a server via it’s direct IP, or a domain.
