Thanks everyone. I guess I did not look close enough at the PS2 to seeit had an optical.
Also, I will use Gonks advice on hooking up the analog audio inputs, as I am using all of my optical inputs, now that I got a PS3 for Xmas!
Woo Hoo!
Now I have to go get Guitar Hero for the PS3 on Wednesday for the kids (and me too)
