Need Help Booting DVD-r backups!!

[sjaved]

hi all
ive got a Pal PS2 alongwith a USB Sbox Modchip. I need to play the Final Fantasy X Dvd-r and i use a AR2 V2. All the CD-r backups work fine, but i dont know how to make the FFX dvd-r work. The only original game i have is Zone of Enders, but all the methods ive tried dont work(the holding the RESET button and shit). Any ideas on how to make it work???

USB mods don't have enough internal wires to control the disk tray for the doble swap. You cannot play DVD-Rs with a USB mod. Sorry.

(well you can if you want to shove a knife in and twist it in the guts and hope it hits the eject pin and not the laser!)
