making a DVD from a Windows Movie Maker Project File

I don't know what format to make a movie in that will play on a DVD player.
I thought a DV-AVI is what I'm supposed to do. The computer won't let me
Finish Movie as that file type because of space, and it won't accept an
external hard drive destination that has plenty of space. All the clips have
already been saved to the computer as Windows Media Audio/Video files. To
compound matters, the clips all seem stunted and don't have the video and
audio syncing properly. But in the project file, they seem fine. I have
Power Producer, which indicates it can make DVD movies, but I doubt it will
take a Windows Movie Maker Project file, and all the clips seem screwed up.
I'm obviously a bit of a beginner, and I'd really appreciate some help.
Thank you.
