uses a square pixel (1.0 x 1.0). If you were to create a DVD menu

on a computer and import it into your DVD authoring software,

the menu would be squeezed horizontally and appear elongated

Your graphics must be designed with the non-square pixel

especially if you have Photoshop™ CS or CS2. These versions

of Photoshop come with a series of templates that allow you to

design a non-square pixel menu on the computer.

and each has it’s own template. To keep things simple, we will

to 24 bit color by selecting “Mode” in the “Image” menu.)
