When I get a new disc, I first make a decrypted backup of the disc. This results in a folder that contains all the contents of the disc with the encryption removed. Then I open the folder with MakeMKV to see all the titles on the 'disc'.
Code: Select all
makemkvcon --progress=-same --cache=1024 --minlength=0 backup --decrypt disc:0 backup
I tried that now and 'backup' was actually able to backup the disc!
So in the next step I then tried to use makemkv to convert that backup to mkvs:
Code: Select all
makemkvcon --progress=-same --debug --cache=1024 --minlength=0 mkv file:backup all mkvs
but now _this_ command seemed to get stuck for hours.
strace (without any options other than -p to attach to the makemkvcon process) shows only nanosleeps, no other activity, but I have no idea whether it should show anything else.
So I think a problem with the BD drive can now be eliminated as the cause of the issue, right?

From there, I use
MPV on the command line to play the relevant #####.m2ts files for the various titles. (Lots of players would work, I just like MPV.) From that I can sort out what's interesting and what isn't, then I rip the relevant titles. This ripping is as fast as my storage will go since it isn't coming from an optical disc.
I tried that but the quality seemed worse than playing the mkvs I had previously created, it looked kinda bad, possibly "telecined"? I’m not so sure about these terms … Every second line seems to be "delayed" or so when there is movement. Do you know anything about that?
Also: How do you get from a m2ts file you want to the playlist/title number you need to extract?
And how do you extract those titles then? With 'makemkvcon mkv'?

Do you have a different drive you can try? It has been my experience that some discs just don't work in some drives.
No, I’m not in the habit of having hardware lying around (; I guess I could try the drive that’s in my (currently defunct) desktop. It might be a 'Lite-On iHES112' but I can’t currently tell.
But the behaviour described above seems to indicate that the problem is not with the drive anyway, doesn’t it?
Right now I’ll just leave makemkv running on the 'backup' folder. It seems to be doing _something_ as 'htop' shows it using 100% CPU (of one of the two cores) even without it showing any progress.
I’ll report back when it’s finished or in 1-2 days, whichever comes first :D

In your case, do you know if title_t04 is even interesting to you?
I think I figured that out: it’s moderately interesting. I can easily live without it but since the issue seems to be with makemkv and could possibly reoccur with titles I really want to have (until it’s clear what’s causing this behaviour, I currently don’t want to just ignore the issue and move on.
But as I said: I’ll leave it running for 1-2 days and then report back.
