Hey Marty, I flashed my BU4ON to MK1.03 and it still works but when I insert a UHD disk the drive icon in makemkv just never stops spinning. I also tried flashing the BU4ON 1.00 and the buffalo BU firmware and I get the same result. do you have any advice? I tried it with two different UHD disks but that is all I have at the moment. One is a retail movie, and the other is the same movie decrypted on a verbatim BDXL M-disc.

1. Clean the discs.
2. Always let the os initialise the disc first, then open MakeMKV.
3.ensure MakeMKV has internet access so it can download the hashed keys database and updates as required.
Cheers :D

Just flashed my BP50NB40 to the BU40N 1.00 firmware, using the SDF GUI tool in Win11 with instructions provided previously. Ezpz.

Problem is, MakeMKV now reports "The program can't find any usable optical drives."

WTF?

after a power cycle, all seems to be well again. That was odd though.

It's now a full LibreDrive, yay!
