How is this DVD made?

Heya,

Recently I’ve had a client come to me trying to create a DVD that will play on a set-top box dvd player. He wants to be able to play DVD video with scrolling text and matching PowerPoint presentations for deploying Distance Education videos. Here is a JPG of a competetors DVD disc that has basically what he’s looking for. Does anyone know how this sort of DVD could be created? What application would I use? Thanks-
