Is there anything about the debian / OMV install that would impact the ability to make use of optical disks?
I confirmed the disk is listed in my BIOS at boot, so there is no SATA issues etc.
I created a new stack for makemkv, and as it suggested I left out the device lines from the config, in order to view the log and help identify what the devices are to be added.
nothing was listed in the container log that spoke to optical disks, leading me to wonder if the OS sees them at all.
