I am having trouble making back ups of my ps2 games. I am using dvd decrypt to read and then to write. It all works ok when I write the file to my dvd+rw disk. I do this before putting it on my dvd-r disk to make sure it works first. But when I put it on my dvd-r disk I make coasters. I burn at 1x to make sure it will work but for some reason as soon as I put it on the dvd-r disk it wont work. I am using memorex dvd-r 4.7 gb 120 min 4x dvds , any help?
