I have Plex for Samasung version 3.3.3 and tizen 2.4.0. When trying to play h265 content plex always wants to transcode to h264. I have modified the “samsung smart tv” profile to accept h265. When I play the same content on Roku Plex it has no issues and does not try to transcode… Here is the info on the media I am trying to play…
