check www.megagames.com/ps2 for turtorials.. or search here.., anyway you need 700mb cds for games that are bigger then 650 and smaller then 700 and 650 for games smaller then 650.. You only need to have a dvdburner if you want to burn dvd backups like ace combat 4 (really big)for ex. but you can put the most of the dvd games on a regular 700mb cdr because most dvd games ain't filling the entire dvd and they will fit on a cdr..
