SHA1 of Unit_Key_RO is 'EA83BE5875ED350EDD7A98ECC9C67DD235CE442C'
Is this rather a hardware/disc related issue or encryption?

MakeMKV is stuck at 'Processing BD+ code'
I assume it's related to decryption then?

you are using 1.03MK?
it says direct disc access mode for 4k you need libredrive on the BU40N

I added some more information. Yes firmware is updated to 1.03MK
I ripped some UHD before and had no problems. I just wonder what's the issue here. Doesn't really seem to be a problem with the disk itself but rather en/decryption.

It's not a decryption/encryption issue. If it was one, you would've never gotten to the screen to pick out the titles. Offset errors are usually indications of a bad disc/drive.

The drive is not bad. I just ripped another UHD before and still got it here. I put the other one in to see if there are any issues but there aren't. However will try to do some backup of 'IT' now. Maybe that works for some reason or not.

Code: Select all

Using LibreDrive mode (v05 id=866A98CB9C4E)
Loaded content hash table, will verify integrity of M2TS files

That's what Backup Mode is telling me as of now. Will let it run for a few hours.

i think the problem may be because
Using direct disc access mode
instead of libredrive mode

i have never seen makemkv do that
also the BU40N can have trouble with 3 layer discs if it does not have enough power hook it up to a high power usb hub or 2 separate USB ports if you have a USB BU40N if internal then idk try having laptop plugged it.
