Used HandBrake for years but wanted to start reducing the DVDs on the shelves, then realised support not there to rip normal DVDs by default… you need to install what’s needed to decrypt them.
Theses links good for background
so in short:
get the latest Handbrake
sudo apt-get install handbreak
get the DVD encoding bits from VLAN
sudo apt-get install libdvd-pkg
sudo dpkg-reconfigure libdvd-pkg
and not sure if you 100% need this, but for good measure
sudo apt-get install libdvdcss2
then you should be good to go. All of a sudden those DVDs you couldn’t “Open Source” with with Handbreak now open. For us, with only one DVD/BluRay player in the [front room of the] house is going to change things so much because we like everyone, stream from anywhere!
