The key to finding the best DVD authoring program, whether it is free for download or costs money, is to find a nice balance between ease of use and number of features. You want to be able to create several menu systems, have transitions between them, the ability to fully customize the menus and add media to those menus. All authoring programs will allow you to put video onto a DVD, but not all of them will allow you to have a full creative project with your DVD.
