The goal is to provide an easy-to-use, yet powerful and complete interface to generate DVD menus, slideshows, and videos to burn on a DVD.
Installation on Ubuntu
You can install it from the Application menu. But I recommend to install it from the command line, so some optional tools used will be installed as well.
sudo apt-get install qdvdauthor transcode toolame dvdrtools
Check out the applications web page for some menu templates and user guides.
