I just saw this error for the first time. Tried the DVD in 3 completely different systems (different computers with different drives) and all produce this exact same error message first (followed by lots of others like "Calculated BUP offset for VTS #0 does not match one in IFO header" when trying to do a backup to ISO. I was also unable to Open the DVD in MakeMKV to rip any titles. However, it will play perfectly in VLC Media Player on Windows 10 and 11 Pro but not Fedora 44 Workstation (each OS on a different PC with different optical disc drive).
I've noticed something that may be related and is likely a problem in MakeMKV. I've had far more trouble with discs that have those "Interactive PC" features or whatever they're called. I suspect there is something with discs that are made for both DVD players and computers that causes trouble for MakeMKV.

You can try dvdbackup (on Linux; or build it with mingw using msys2) -- although it doesn't give you an ISO but just the files.
And if MakeMKV also has issue remuxing the decrypted backup made with dvdbackup (and if MKV is what you want ultimately), try mkvtoolnix or even ffmpeg.
