MakeMKV V1.10.8 does not do the work around for when the disk region does not match the drive region. It says you need to change codecs or download drivers.
Since I have done this in the past, I reverted back to MakeMKV V1.10.7. As usual, in the mismatch region case, it attempts a work around which almost always solves the problem.
The new version should do the work around.
