 |

Just ran into this problem tonight, and the the fix on the MakeMKV forums.
Versions of MakeMKV greater than 1.10.8 will require that SCSI generic support be in your kernel (compiled or module is fine).
The kernel config is CONFIG_CHR_DEV_SG, and when built as a module, it is "sg" and will be loaded automatically.
SCSI generic just gives fancy /dev/sg* to existing SCSI devices, such as your hard-drives or optical drives -- that's it.
MakeMKV looks for /dev/sg* instead of /dev/sr* now.

Just ran into this, I have, and have had, sg compiled as a module but for some reason is no longer automatically loaded on my system. Might be a systemd change.
worked fine

He posted on it on the MakeMKV forums the reason for the change, and it made sense in my head at the time. Apparently he's accessing the content directly through the SCSI device instead of the filesystem.
Or something. It's over my head.
