Cant Boot FFX INternational Original on V4 US PS2 w/Magic 2

[Spicules]

When I try to boot, it goes to the screen where u can select browser, but I can hear actviity and cant select anything. After about 15-20 sec, those red cubes come up and it says "Please Insert a PS2 disc". CDR copies work fine, Ps2 Originals and DVD Games and movies work fine. Tried with the alternate boot procedure, but still no luck. Any help greatly appreciated.
