I can open the disk in Explorer and see that there's AACS BDMV and CERTIFICATE in there. I'm really at a loss, since before rebooting it worked just fine. I was having some trouble with read errors, it couldn't rip this disk. Maybe the drive is failing?
Windows has stopped telling MakeMKV that there are optical drives. They key is finding out WHY.
If it persists across a reset (not just reboot; a power-down restart that resets the hardware itself), check your permissions; Win10's Fall 2019 update adds rules that exclude a lot of programs from having access to hardware, in the name of "ransomware" protection.
There is a driver you can install with v1.15 and later to make it so that MakeMKV doesn't have to be run as an Administrator. That DRIVER has to have admin rights, but MakeMKV can be run as a normal user if it is running. I have not personally tested it.
@mike, does it make sense to loosen the permission for everyone, would it be better to limit it to a group that one has to be a member of and if one runs MakeMKV without being in that group it asks you if you want to add yourself to the group and temporarily raises privileges in order to do that?
