Thanks for providing a suitable disc dump file. The 8F66 variant of 2046 has been added to the public keydb.

If you haven't previously configured MakeMKV to utilise the public keydb you can follow my instructions here or use SamuriHL's utility for Windows (Link)

Thanks for letting me know. Your original disc dump had an incomplete verification data file. Could you please delete your original MKB20_v82_2046_8F66.tgz file, reboot your computer, and have MakeMKV generate a new disc dump file for your 2046 disc? Post the link to the alternative disc dump file when you get a chance.

The media key (MK) is definitely correct but the volume ID may be invalid and that would lead to an invalid unit key which prevents playback/decryption.

Thanks for recreating the disc dump file. It is interesting that there is still no verification data...

Could you please make a protected backup of the disc with MakeMKV? After you have made the protected backup, please upload any small M2TS file from the BDMV/STREAM path and post the link here. Don't just copy a small file directly off the disc in case bus encryption is still active.

If there is no suitably small M2TS file, you can copy the first 2-4MB of the largest file with a tool such as dd or HxD and upload that instead.
