The exact message I am getting is Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' occurred while issuing SCSI command AD010..080002400 to device 'SPTI:\Device\CdRom0'

I am running 1.9.2 and using a BD-ROM ASUS BC-12B1ST internal BD drive.

It is the same on all of my Blu Ray discs even ones I have already ripped before.

Ripping DVDs still works.

You most likely inserted a BD recently that has AACS v54 on it. If so, the decryption keys used by MakeMKV have been revoked. Once that happens, the drive will refuse to decrypt ANY BD disk, until MakeMKV is updated.

Mike has said he is aware of this, and a new version to fix it will be "coming soon". No date has been specified.

That's exactly what happened.

Thanks.
