Is your user part of the cdrom group?
if you do "ls -l /dev/sr?" you will likely get something like this
brw-rw----+ 1 root cdrom 11, 0 Oct 7 19:39 /dev/sr0
brw-rw----+ 1 root cdrom 11, 1 Oct 7 19:38 /dev/sr1
As you can see root is the owner and cdrom is the group (in fedora at least) and both have read and write permissions.
If your user is part of the cdrom group you can use the device easily.
And the '+' means there are extended ACLs in operation, which can be shown with "getfact /dev/sr?"

I have a blueray-writer drive and installed(makemkv) from arch but the drive is not recognized.
ls -l /dev/sr?
brw-rw----+ 1 root optical 11, 0 Oct 15 08:47 /dev/sr0
MakeMKV v1.15.3 linux(x64-release) started
The program can't find any usable optical drives.
What is the command or commands to fix this please?
I just installed it via yay makemkv so I haven't actually done anything other than that.

That tells you the group owning /dev/sr0 is "optical".
You need to make your user part of the optical group if not already, then you should be able to see a disk in the drive and use it.
The user running makemkv must have access to the drive before makemkv can use it, so this step is first.
Using the "groups" command will tell you which groups your user is assigned and using
Code: Select all
sudo usermod -a -G optical exampleusername
will add the example user to the optical group. After adding the user to the new group it will be necessary for that user to log out and log back in before the change is effective.

Sorry I ran the command you put,
Code: Select all
sudo usermod -a -G optical thetester
and rebooted however the problem still exsit's.
Code: Select all
@AdminPC ~]$ groups
sys network scanner power rfkill users video storage optical lp audio wheel thetester
Wondering if makemkv should be run as sudo or something like that.

Drive not been found is a common problem, here is how i fixed it on Manjaro
Open a Terminal, Note: running with sudo does not work
su root
Enter your Password
echo sg > /etc/modules-load.d/sg.conf
Exit
Reboot
After this my drive has been found (pioneer drive)
This also helps for Nero not be able to find a usable drive.

Just upgraded to version 1.16.4 for windows, and the program now cannot find any usable optical drives.
Previous version worked fine.
I can see the drive and play the bluray so I am not sure how I can fix this.
Can I use the previous version again?

You're asking in the Linux forum.
Windows has issues where newly-installed programs that haven't been blessed by Microsoft will not be given access to removable drives. A search for "ransomware exception" will come up with how to grant MakeMKV an exemption from that policy.
