Today I submitted a dump file to svq@makemkv.com for Twister 4k UHD (MKB20_v77_Twister_468C).
I was having a problem with makemkv on an Intel machine running Fedora 40 Linux giving me errors as follows:
"Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT PRESENT' occurred while issuing SCSI command"
but I was able to successfully rip the UHD blu ray with the same drive and disc using an AMD 5500U machine running Windows 11.
So, I am not sure if this problem is a Linux vs Windows MakeMKV, or with the operating systems themselves. I can provide more details for anyone who is interested in picking this apart further.
I am not a programmer or IT specialist in any way. Just trying to get things to work.
I apologize for subitting this dump again, as it was already part of the key file and worked fine.
