OK, now, I own two Macs as well, but I have a problem with the use of the pejorative "Windoze". I'm happily dual-platform. Windows XP isn't as evil as its predecessors, but having said that, I'm frankly rather disappointed in the way Vista is going, and I am currently not planning to license Vista for any of the computers that I personally own.
But enough of that. There are actually some great editing and DVD authoring programs for Windows--many more choices than are available for the Mac. And the good thing about Windows software it's much easier to find trial versions, so you can see what software works for you (as far as workflow and capabilities) before you drop any money on a particular package.
While I am prevented by policy to make an explicit recommendation, I can make a shameless plug for our online buyer's guides at
