Verbatim 43888 reads normal Blu-Ray fine, AACS/LibreDrive issues with UHD...

Post by standard_output »

The drive is able to read normal Blu-Ray and 4K/UHD discs (e.g. listing contents) without issue.

MakeMKV is able to properly process normal Blu-Ray discs without issue.

All 4K/UHD discs that I have tried result in comparable failures, as described below.

I suspect the next step is drive flashing, or perhaps waiting for MakeMKV to put out a patch - not really sure. Any help appreciated.

MakeMKV v1.17.9 win(x64-release) started

You need to flash it. BU40N 1.03 is recommended.
