Yeah, that definetely makes sense.. And the Quality is great, its the same disks I used before with my internal burner (which is now broken) and they all work perfectly fine. The sketchy part about all of this is the disks im burning work SOMETIMES... like a 1/10 success rate if i keep opening/closing my xbox tray. Thats why I assumed that it was the Book Type but I'm honestly unsure. I'm not so great with this stuff.
