I not really sure if this is possible and how costly this is but what if you install some version of linux on your ps2 that has the ability to share file like windows computers can do. Then you use a hub, router or other networking device to connect your computer and ps2. Then share the ps2 DVD drive and then mount it on your computer by mapping a network drive with windows. You will probally need the eathernet adaper of the ps2 (not sure how that works or the cost)

I only post this to try to help you out and lead you in some type of direction. this would be intersting if it really did work
