Right, thanks to you chaps i managed to get to a position where i had a 360 image to burn. However the new problem is when i get to burning the second layer it fails. I have a nec 3550a dvd, this has been flashed with the liggy firmware. I use imgburn. i also wasted 2 verbatim duals. So i open file with image burn. I cant do a test as it says its not supported. I start it burning and it goes off not a problem. At the point where it switches layer it fails. i then get the i/o spiel about there being a write error. i have also had power problems on other burns. My power supply is not the problem here. Should i try using clonecd? is the combination of my drive, medium and firmware not good enough for imgburn? Any ideas people, i cant afford that many discs.
