Well, I’m sorry to say it doesn’t look possible. If you like using Movie Maker to edit than you can just publish the movie as an AVI and import it into whatever software you want to use to author the DVD. Here’s how to make the AVI:
1. Click on Publish Movie
2. Select “This Computer”, Next
3. Choose your filename and where you want it to put the file, Next
4. Select More settings: DV-AVI(NTSC), Publish
