please mark this ticket as invalid.

it looks like makemkv 1.10.9+ requires generic scsi device to probe bluray drives. some distros are creating /dev/sgX device with 600 mode. If frontend runs as different than root user, makemkvcon will exit (due lack of permission to read from /dev/sgX) leaving frontend in non-responsive state. Issue can be solved i.e. by dev rule setting /dev/sgX mode to 660.

Sorry for false bug report!
