Using /dev/sr0 in AppVM required to passthough a sata controller, but in this guide I use dom0 instead. Because I currently don't have any USB optical drive or second sata controller, I'm using laptop. So caution ahead.

Read more about optical drive in Qubes OS

Step 1: Launch terminal in dom0 and update dom0, then install dvdbackup and regionset

sudo qubes-dom0-update
sudo qubes-dom0-update dvdbackup regionset

Step 2: Install libdvdcss from remi's in rpmfind, you don't need to config rpmfusion or any extra repo in dom0. libdvdcss is needed to read most movie DVDs

In sys-firewall terminal

curl -s https://rpmfind.net/linux/remi/fedora/37/remi/x86_64/libdvdcss-1.4.3-1.fc37.remi.x86_64.rpm -o libdvdcss.rpm

Step 3: Close sys-firewall terminal, then execute this below commands in dom0 terminal

qvm-run -p sys-firewall `cat libdvdcss.rpm` > libdvdcss.rpm
qvm-run -p sys-firewall `rm libdvdcss.rpm`

Step 4: Install libdvdcss.rpm in dom0

dnf install ./libdvdcss.rpm

Step 5: Read regionset and dvdbackup documentation and enjoy ripping
