NOTE: Please use DVD-R's for your iDVD projects. This will ensure a greater likelihood that the finished DVD will play on most DVD players.
These instructions assume you are using iMovie 11 and iDVD 7.
1. Insert a blank DVD.
2. In iMovie, click on the Share menu and then iDVD. The movie will take a few minutes to process.

3. Your exported movie will open in iDVD and automatically create a new project with the default theme.
4. Change the titles and play menu by clicking on the text (the button you select to start your DVD when in a DVD player or computer)

5. Choose a theme for your DVD menu page.
6. When you are ready to burn a DVD click on the burn button. (Try a different theme if you encounter problems burning the DVD.)

* Please test play your DVD to make sure that your entire movie was burned correctly onto the DVD.
