Software to archive personal DVD library
My favorite is handbrake which is available for Linux, mac and windows.
Make sure you have restricted extras and DVD play capability configured https://vrpc.com/showthread.php?tid=19.
From the terminal:
1. sudo add-apt-repository ppatebbins/handbrake-releases
2. sudo apt-get update
3. sudo apt-get install handbrake-gtk
the newly installed software can be accessed in the sound and video application menu or by using the launcher search feature for handbrake.
