I have now released my MPV fork for the Lume Pad 2.
Main difference compared to the jakedowns variant is complete support and proper rendering of full/half SBS and TAB in any aspect ratio.
3D rendering of text based subtitles with configurable depth, position and size.
Auto detection of format and auto enabling of correct 3D format.
Demo video:
Do make sure tyou download the latest version 
Thank you very much for the application. It’s great. Is there a setting that needs to be made so that the subtitles are automatically downloaded from the directory where the movie is? Thank you
You are welcome
Not really sure what you mean. If you open a video from a SMB share using for example CX File Explorer it will try to find a subtitle file mathcing the video files name in the same folder. Like movie.3d.hsbs.mp4 and movie.3d.hbsbs.srt.
Make sure you are using the v0.3 version.
Thank you
