Hello,
I’m new to plex and going through the first time setup as a player consumer of Plex. Just raising a potential issue which came from a reddit post.
Plex Media Player is an older, discontinued media player. Its final version was 2.57.0 (from 3’ish years ago), and it is no longer being developed. It is not new and I would not recommend using it at this point.
It was effectively replaced by two different, new clients: Plex for Windows/Mac/Linux and Plex HTPC. Plex for Windows is the desktop client, intended to be controlled by a mouse and keyboard. Plex HTPC is an HTPC app, with a 10-foot interface and intended to be controlled by a remote.
