How have you extracted the ISO from the Xbox360 disk to your PC?
rgds, soso

sounds like you got lots-o-reading to do. you have to "build" the image to burn to a disc. definately a lot more in depth than the original xbox.
try the tutorials section and check out google.

We need more info like 360 drive you got firmware...etc.
I use Xbox Backup Creator to make my owned games backups.
With that it will read (save) game image to pc then it will write (backup) to a DL disc.
Its pretty easy and fast.
