Here are the notes from the release:
For those who are wondering what a Single Dolby Vision Layer is:
Dual Layer .mp4 remuxes can’t have Dolby Atmos.
A Single Layer .ts remux has Dolby Vision & Dolby Atmos, but some players may not be compatible with it.
This is a Single Layer .ts remux, playable by latest Plex Beta on Nvidia Shield 2019, MPC-HC and LG Internal. This release also
keeps the Enhancement Layer (FEL) intanct with profile 6 so it will probably not work on ATV which only plays MEL.
Is FEL not supported in Infuse either? Using latest beta.
