First off, you can work with the program's timeline, which is very similar to the one found in Adobe Premiere or Final Cut. Obviously you won't have the same options, but you can enjoy its familiar design.
Once you've done this you can create the different DVD menus, which you can easily link to one another, also adding images, text, etc.
Lastly, the program asks you to choose a name for the DVD and the writing speed you want. When all of this is ready, just click 'Create Video DVD' and that's it.
