Anne of Green Gables from The Collected Works of Director Isao Takahata / VWBS-8214
This release contains decrypted MGVC (Master Grade Video Coding) enhancement layer under the KDM folder.
Each ISO can be played back by Panasonic devices even in decrypted form, or compatible playback tools can decode a 12-bit 4:2:0 output.
MGVC: http://www.avsforum.com/t/1486405/36-bit-mgvc-blu-ray-only-in-japan
Due to how files are stored, an ISO is required to keep the virtual sector mapping on the .extif MVC stream without blowing up the size.
See /KDM/EDL.bin (XML text file) for a description of the virtual mapping.
Playback programs can use an H.264 MVC decoder and merge the planes according to [Patent US9392246B2](https://patents.google.com/patent/US9392246B2/en) or [Patent JP5914888B2](https://patents.google.com/patent/JP5914888B2/en) to get 12-bit 4:2:0 output.

Hi, Thanks.
If I understand correctly, it’s not possible to play these Blu-rays on your computer using mpv, VLC, or other dedicated software, even if the ISO file is mounted, is that correct?
You need special software to decode this. I have listed an example script that works under Linux to output raw video https://git.gammaspectra.live/WeebDataHoarder/pana-mgvc#decode-mvc-sh using the reference H264 JM decoder and some programs to reassemble it.
MPV or VLC (or ffmpeg) do not support H264 MVC, as such they cannot directly decode this. The above program can generate a playable raw video stream, but it's mainly useful for encoders (it's a 300-600GB file depending on movie).
