I have a sh-d162c and using xbox backup creator. I have kreon V1.0 and xbc v2.7 build:0265. When a disc is inserted into the drive xbc says this is not a true 1 to 1 copy of the image. What does this mean?

Are you burning with the correct Layerbreak and etc..?
I assume since you're using the sh-d162c you must know what you're doing.

1 - Wrong Forum
2 - Did you even read his message ?
3 - The Answer - This is not a 1:1 copy means that XBC rebuilds the iso to be iXtreme compatible. a 1:1 image would not work. Everyone gets this message it is completly normal to get it. If you want to test your image after creating use ABGX
