To see the size of your project:
Choose Project > Project Info.
You can monitor the size of your iDVD project in the Project Info window. It shows the total duration of your project, as well as how much space is used by the elements of your project, including the slideshows, movies, and menus.
Choose Project > Project Info.
The total size of your project, in running time (in minutes) and in size (in gigabytes) shows below the Capacity meter on the far right.
The Capacity meter shows how much of your project’s total size is used by each of its elements. The bands of color indicate what proportion of the project each element accounts for.
The numbers below DVD-ROM, Menus, Slideshows, and Movies specify how much space (in gigabytes) each uses. Click these numbers to switch the display to show the number of these items in your project and how many tracks they use. An iDVD project can have a maximum of 99 tracks.
In general, the amount of content your iDVD project contains correlates to the quality of your burned DVD. The white arrow in the Capacity meter points to the quality your burned DVD will be. Quality is highest on the green portion of the Quality meter.
