It should work fine in mkvtoolnix or tsmuxer as long as it’s a .w64 and not a .wav - at least, that’s what I did with v2.0 after converting the .wav to .w64.
Still no clue how to get it to burn to a BD50 and work in a PS4, though I do now have a standalone UHD BR player and haven’t tried it on that (waiting on v2.1 before I waste more discs).
