We can make (and have made) virtually any type of DVD out there. The most common is the DVD-5, which holds roughly 4.8gigs of data. We can also make DVD-9's and 10's, which carry more data. We do offer authoring services for DVDs, however we find that people have the greatest levels of success when working with people local to them, ideally involved in the project. We are happy to help though, if the situation requires it.
