I think the basic point of the thread was that DVD maker under Vista just does not like, and likely will not run, on the Emulated hardware presented by a Fusion Virtual Machine.
For many reasons, Fusion simply might not be able to Satisfy DVD maker with the hardware it "fakes" for Windows.
If you MUST use DVD maker, a Boot Camp installation of Windows would provide more "direct" access to your Mac's video hardware, which might be capable of satisfying DVD makers' stiff requirements. But it might not. Better chance of it happening in BootCamp that in a Virtual Machine, though.
Might I suggest, however, that since you have a nifty new Mac, that you explore iMovie and / or iDVD? Never mind that they're just far and away 'better' than anything Microsoft has to offer... they're OSX native applications, and very well integrated with OSX. A Native application will ALWAYS run better than something "Emulated" or "Virtualized"... regardless of the quality of the application.
Take advantage of all your Mac has to offer... it's so much more than "an expensive computer that can run Windows"
