I'm trying to burn a Xbox 360 iso, in a DVD+R DL. Therefore i need to change the booktype to DVD ROM so that it works. The problem is my device is not in the list. I have two options: MATSHITA DVD-RAM UJ-875S (ATA) or Optiarc DVD RW AD-7700S (USB). Either way it wont work. They both work with Doyble Layer but still burn the isos as if they where DVDs (and not DVD ROM) and they dont work properly in the xbox. any help? thanks
