I reinstalled makemkv on my server with a 700W power supply and a USB-C to USB-C cable, and it reads the UHD without any problems.
I don't know what insufficient power has to do with the inability to decrypt it, though.

What is the advantage of copying the keydb.cfg file into the .makekmkv folder?
There's a keydb-deu and a keydb-eng file. Should I use the keydb-eng file?

I downloaded and started the keydb helper.

It writes the keydb.cfg file to the folder
C:\Users\name\AppData\Roaming\aacs

The keydb website says to copy the keydb.cfg file to the following folder??

C:\Users\name\.MakeMKV
Which is correct?

I also bought a Verbatim 43888, flashed without any errors and was able to rip an entire BR (FullHD; not UHD) but when i try to open it using Pot Play or VLC, it doesn't work.

If it matters, i have a paid license for MakeMKV.
I saw something about public keydb but i'm too noob to know how to properly do it.

VLC gives the following error:

Thanks

The disc will be played without menus.

Hum, not sure what you mean about that.

I made a backup/rip without any issue but then I wanted to try to play the BR (not the MKV file created).
After going to "Preferences - Integration", I checked all the boxes ("C:\Windows/System32", "C:\Windows/SysWOW64" and "C:\Program Files\VideoLAN\VLC") and now I'm able to play the BR on VLC but it says:

Java required:
This Blu-ray disc requires Java for menus support. Java was not found on your system.
The disc will be played without menus.

I thought that installing Java was already something from the past. I'm using W11.
(and playing, without menus, the video freezed twice after 1.xx minutes. Now is playing consistenly)

Either way, I don't use VLC; I always use Pot Player and even with the integrations enabled, it doesn't play (don't know how to post here the error log without using too much space)

Yes, MakeMKV does use Java and probably VLC too. I don't use VLC so couldn't say for sure.

C'mon Marty, i'm noob but not that much

I don't want to play BR with this drive (it's the only one i have) but tried and it didn't worked so i was trying to know why and how can i solve this.

Thanks

Then regular Blu-rays would probably have the same problems, right?
