Burning DVDs off of iMovie ver. 2

Hey all. I have a Mac G4 with os 9.1. I am trying to burn video dvds off of iMovie v.2.0.3. Have created the project, but can't get my Lacie firewire DVD burner to find and burn the project.

I exported the project to Quicktime, and can view it there, but I have been unable to get my Lacie drive to recognize the project and burn the DVD. I can burn data DVDs, but not videos. I also cannot find a format through which I can put the project on media and open on my Windows computer to burn the discs.

Is there any way to get my project onto a DVD? Answers?
