Ripping an encrypted 4K Blu-ray (TMNT 2)

[sephirothkefka]

I recently got the TMNT 2 4K as part of the TMNT Trilogy boxset and 1 and 3 ripped fine. However I've had consistent issues with 2 as it occasionally fails to read and when it does read MakeMKV gives a "UDF" error and seems to either hang while attempting to decrypt the disc or throw an "unable to decrypt error. I've gone through 3 replacements and they've all done the same thing. Copying the disc via Xreveal was fruitless as it didn't appear that Bus Encryption was being enabled (despite the fact i have a Pioneer 4K drive on the supported fw) and even then the disc still wont open despite the keys seemingly existing in my keydb.cfg. On a hunch, copying the files via Windows also was fruitless as it had the same result. Is there anyway to try to rip this disc? I've thrown my hands up at this point and I honestly don't know what else to do.

Not sure what the problem could be if multiple copies have done the same thing. I had no issues using my Docker container of makeMKV on my Ugreen NAS with that title. Have you tried to reinstall makeMKV. You might want to try a different drive if you can obtain one and its always a good idea to have multiple drives as risk mitigation.

Possibly try to backup the disc with the decryption option disabled then open the backup. Arrow didn't encrypt several of the Stranger Things UHD disc. Solution was to backup the disc with decryption disabled then delete the AACS folder and open the backup file in makemkv if I recall correctly. See the Stranger Things UHD thread.
