Yup, I guess so, since that's a hardware limitation of your present Video chip, you need a card that supports higher than the requirements for PSE.
Thanks, I finally figured that out. Ordered a EVGA nVidia GeForce 7200GS 512 MB VGA/DVI and hope that will work until I can get another computer. Once I get it installed I will write in and let you know how it works. Things are a little flaky now on the PSE Premier movie editor, too.
