Blu-ray disks play in MakeMKV on one Linux Mint computer but not the other

[GNU2Linux]

I'm happily using MakeMKV on my laptop running Linux Mint 22.3. I installed it through the PPA and have the beta license key. Laptop has an internal Matshita Blu-ray drive model BD-MLT UJ240AF. It says Bus Encryption flags 1B for what that is worth and Highest AAC version says B2. I also have VLC installed and also previously installed the libbluray2 and libaacs0 libraries and did sudo ln -s libmmbd.so.0 /usr/lib/. It plays Blu-ray disks in VLC just fine and is able to rip Blu-rays without issue.

In contrast, on my Linx Mint 22.3 desktop, I have a 5.25 inch internal Blu-ray player HL-DT-ST model DVDRWBD CH30N (Firmware date: 2115-10-13 14:48). It says Bus encryption flags: 1E in MakeMKV, fwiw. I also have VLC installed as well as the libraries and everything same as above. Blu-rays are not reading or playing in MakeMKV or VLC on this desktop. Not sure what steps I should take to get it working. The below information is also showing in the desktop MakeMKV interface in case that is useful.

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

Any suggestions are appreciated.

I'm not sure if 1E means the drive does bus encryption (for BEE discs) but if that's the case, most likely you'd need to flash the drive with an MK firmware so that it becomes a LibreDrive, but I have no idea if this model you have can be flashed. With platform being MT1959 there's at least a chance that it can be, I guess.

Or if bus encryption is NOT the problem here: have you forgotten to set the sdf_Stop workaround on your desktop? Supposedly you need it for non-LibreDrive with MakeMKV 1.17.7 or above on Linux.

I followed the advice in the following article on the OMG Ubuntu web site last year to get the Matshita Blu-ray drive in my laptop running Linux Mint 22.3 to work with MakeMKV and it has been working for me reliably to play or rip disks. https://www.omgubuntu.co.uk/2022/08/wat ... th-makemkv

Now as far as for my Linux Mint 22.3 desktop, where it isn't working, I don't know what you mean by "have you forgotten to set the sdf_Stop workaround on your desktop?". I don't recall doing that for my laptop, and I'm not aware how to do it for my desktop. Nor do know anything about flashing a drive with MK firmware to make it a LibreDrive, although I'm willing to read a guide that explains it if it's necessary.

Actually, can you check "log debug messages" in preference, and then post the content of ~/MakeMKV_log.txt (NOT log messages in the MakeMKV window) as code blocks from both the desktop and laptop after attempting to open a disc in MakeMKV (NOT VLC)? (If it stalls at some stage before you can even click open disc then please also describe the stage it stalls at. Either way, post the log. Preferably also the LibreDrive information of the laptop drive, if any.)

It would help me to tell what exactly is going on there and how exactly to preceed with the sdf_Stop workaround you might need here anyway.

P.S. Apparently there's no MK/LibreDrive firmware exactly for the drive you have. While it seems that you have a somewhat "weird" one (as in, an old model with "modern platform"), which perhaps makes it technically possible to become LibreDrive through one way or another, it is at the same time difficult to draw enough attention from people who can make it happen / know what to do, especially when things are not as "vigorous" as it used to be anymore. So perhaps forget it for now.
