To archive your iDVD project:
Check the file permissions for the media assets (photos, movies, and so on) in the project and set them to Read & Write if you want others to be able to open or copy the assets in the archived project.
Choose File > Archive Project, and then click Save.
Type a name for your archived project.
Locate the folder where you want to save the project.
The size of the current project is displayed in the Archive Project dialog.
Click “Include themes” if you want to archive the theme or themes used in your project.
Select this option if you are using customized themes that might not exist on another computer.
Click “Include encoded files” so that the project files won’t need to be reencoded after being moved to a different location.
If you want to save time and hard disk space, however, leave this option unchecked.
Click Save.
A progress bar shows that your project is being archived. The larger the project, the longer it takes to archive.
Your project is saved with the word “Archived” in the file name.
