MakeMKV is the only utility that I've found that is capable of playing (and copying) Blu-Ray movie releases on any Linux, including Ubuntu. I'm quite sure MakeMKV can also handle DVDs, so it might be your one-stop solution for the conversion process. It has a simple GUI and a command-line utility. By default the GUI will choose a title (or titles) for you based on some heuristic, and put the corresponding original MPEG stream inside a MKV container.
MakeMKV has closed source parts, which are proprietary software. You can use it for free for 60 days, after which you will need to obtain a license key. This key can be bought from the author (currently USD 50, I think).
If you do not wish to compile the sources, I think you can get an installer from ebower's PPA (it appears to cover everything from 10.04 to 12.10):
sudo apt-add-repository ppa:ubuntu-ebower/ebower
sudo apt-get update
sudo apt-get install makemkv-install
However, I have no experience using that PPA.
Could you also update your question to specify how abcde functionality should be replicated for video content (for example, what should happen to the menus of DVDs, and BD-J / BD-Live features).
