So I have the box checked to allow external players but it never asks me what I want to use when I play the video, it automatically plays the Plex player. Some movies/shows I want to see are h.265 which mxplayer supports and Plex does not so I would like to use it. Thanks in advance!
Not sure, it's a little messier but an alternative solution would be to use Kodi with the plexkodiconnect add-on
