Using Toast Only for OSX

[decksterx]

i only have one drive (super drive) on my G4. So i made a disk image first and copied the dvd game on the disk image. i then dragged the dvd icon on the disk image to the toast window (using toast 5.2 on osx) and burned a copy using a dvdr (fujifilm dvdr's). it doesnt work on the ps2. however i've tried backing up games (cd games) on cdr's and they work fine on the modded ps2. anything i'm doing wrong with copying dvd games? what brand of dvdr's would you recommend? im also in nyc.

thanks a lot!
