I just installed a Magic V modchip on my Version 3 PS2 and it doesn't play my PS2 Back-ups. Everything else works fine (ie. Original DVD games, DVD movies, PS1 original and back-ups) except for DVD back-ups. I keep getting the red screen with the "please insert a playstation or playstation 2 format disk" sign. I'm just wondering if it's the modchip or it has something to do with how I burn the DVDs. I've used Nero 18.104.22.168, DVD Descrypter, and Alchol 120% to both back-up and burn the games but it just doesn't work. Although the PS2 CD back-ups work fine. So is it the modchip (modchip.com says it's only compatible with V5-V8 PS2), is it the software, is it the medium (I've used both Maxell 4X dvd-r and an OEM brand called AN31) or is it the burner (I have an LG GSA 4040B DVD burner)? I think it's the modchip, but if that's true why can I play back-up CD's? Any help would be appreciated, thanks.
