Am I missing some options? PlexVR seems to be extremely limited. I tried playing a Full SBS movie and the app incorrectly gave me a stretched 32:9 aspect ratio for the movie. It correctly played in 3D in that stretched aspect ratio, but tried to play subtitles as well. The subtitles were split between eyes, as though the player were rendering them in the center of a 3840x1080 video and then splitting that output for each eye.
I don't see a way to set the proper aspect ratio or select which subtitles to play (if any at all) in PlexVR. Changing the video quality from Original (1:1) to 720p corrects the aspect ratio, but then the player can't connect to my server anymore (or so it claims).
