Photoshop is not a video program, it is a photo program. But you will notice that 720 x 480 is not the standard 4x3 ratio of TV whereas, 720 x 534 is closer. If you build your graphics at 720 x 534 (it should probably actually be 720 x 540) when you watch it on TV, the graphic elements of your photoshop file will not be distorted after being converted to 4 x 3 tv ratio.

The VV3 manual recommends using a 655 x 480 setting for stills.

This is because Photoshop works in the RGB space, where pixels are square.
DV has a pixel aspect of .909. So to compensate for square pixels, you can either do 655 x480, or 720 x 534. Math works out the same in the end, because either way, vertically or horizontally you are compensating for square pixels in a non-square pixel environment. It's not a standards issue, it's square vs non-square.
720 * .909=654.45 pixels, rounded out to 655. Choose 654 if you are really picky about 1/5 of a pixel.
