Hi. I have been using MakeMKV to create BDMV folder backups of my regular (2K) blurays for quite some time now, which I have been playing on my Oppo BDP-103 without any problems. However, I have come across this issue for the first time when I recently took backup (with decryption ON) of Planet of the Apes 50th Anniversary Edition (9 Movies Collection). 6 out of 9 are giving play error (firmware update issue which I know is not the case). It seems to be a copyright error despite decryption with MakMKV. I am using the latest version of MakeMKV

The particular BDMV backups that are giving playing error are:

1. POTA (1968)
2. Beneath the POTA
3. Conquest of POTA
4. Escape from the POTA
5. Battle of the POTA
6. Rise of the POTA

Any guidance/ help will be highly appreciated.

MakeMKV only removes AACS encryption. No region lock, no BDplus, no BD-J protection etc.

DVDfab Passkey helped for me with such problems. When rightclicking onto the tray icon there's a point for fixing BluRays. That might help you there.
