I hate to burst your math bubble but 840MB is not an increase of 20% over 800MB! The standard CD sizes I have seen are 650 and 800MB, and I have never seen 840MB CDs. If they exist, it is a 5% increase in size over 800MB. If you really need to have larger capacity, you want a DVD burner. DMC David M. Converse www.lumigraphics.com
