I'm burning ISOs created by myself onto these CDs, but they have a 4-8x limit. Anyway, they work when I use the swipe-card and Swap Magic 3.3 way with my PS2, except they're very jerky, and usually result in frozen frames. Very similar to when you have a PS2 DVD with a scratched surface. I'm just wondering whether this is because of my PS2 being unable to read them, the fact that they're being burnt too quickly (meaning I'll just buy 1-4x DVDs), or whether its the DVD make I'm using. Hope you can help me, thanks in advance.
