Nausicaä of the Valley of the Wind from The Collected Works of Director Hayao Miyazaki / VWBS-1531
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.

I have a couple questions about doing these rips. First, will the sector mapping still work with the blown up bin files? If not I'm assuming an alternative to MakeMKV would be required for storing the files as an iso? Most people are seem to say for 3D BDs to make the decrypted backup with MakeMKV then use ImgBurn to make the iso but I'm assuming the files will stay blown up by doing it that way.
The files will stay blown up doing it that way, the disc sectors and structure must be copied as-is. Use AnyDVD/Xreveal on Windows or similar that keeps the sector mapping by making an ISO directly. BD when made without other tricks can be directly dumped as an ISO, so on Linux you can use that (then use tools to strip the AACS using the disk or cached KEYDB).
Alternatively my tool could handle AACS as well via libaacs and your provided AACS keys (then rewrite the sectors) but I don't have the full title key handling yet, at the moment I have a proof of concept where the first virtual stream gets AACS decrypted and MGVC decrypted depending on which piece it is. I use this for directly testing on blurays directly.
Thanks for the info! Back in 2021 I got a DP-UB900-K because I was really interested in seeing how MGVC worked but still wanted to be able to use them directly on my PC. The screenshot comparison on your other post is quite incredible seeing how much more detail there can be.
