Toni found this today (or, at least, told me about it today). The first of a set of recordings done at Würzburg, in Germany. The recordings were made 6 - 7 October, 2008, using NetBeans Platform 6.1 (and NetBeans IDE 6.1) so slightly dated. Still, you should get a good idea of what the NetBeans Platform Certified Training is all about:
If you watch the movie above, you'll see me introduce the course, David Strupl talk about "why use the NetBeans Platform", as well as the history of NetBeans, and more (still watching it myself).
Many thanks to Pavel Kotlov, from Würzburg University, for getting this up on Parleys.com.
