To add to what Postal said...
Pixel aspect ratio is a feature that allows you to automatically correct images that come from, or are destined for, video. Standard definition video uses non-square pixels. They're about 10% taller than they are wide, like little dominos set on their small ends. HDTV pixels are stretched in the other direction, and look like dominos set on their long sides. Computer pixels are square. So, if you're moving a still frame of DV video between the two, it's going to look squished (either horizontally or vertically, depending on which direction you're going, from Photoshop to video, or from video to Photoshop). Prior to the CS version, you had to do the correction manually; now it's automatic.
If video isn't a part of your current project, you don't need the PAR feature turned on.
