Save your movie on a DVD
You can save a movie in Windows Movie Maker as a high-quality video file, and then burn (or write) that file to a DVD using a DVD burner (either an internal or external DVD burner) and video DVD burning software. You can then watch the DVD in almost any standard DVD player.
To save and burn your movie
In the Movie Tasks pane, under Finish Movie, click Save to my computer.
The Save Movie Wizard will open.
On the Saved Movie File page, type a name for your movie, and then click Next.
On the Movie Setting page, click Show more choices, select the Other settings list, click DV-AVI, and then click Next.
Movie Maker will save your movie.
On the Completing the Save Movie Wizard page, clear the Play movie when I click Finish check box, and then click Finish.
Follow the instructions for burning the DVD according to your DVD burning software.
