How to find "Layerbreak=" in IMGBurn

Im new at imgburn, and am backing up an xbox 360 disc of mine. I did the “Create image file from disc” which adds two files to my desktop - an ISO file and a MDS file but when I view either of these files I cannot find the “Layerbreak=” data so I can add the layer break info manually to IMGBurn. No TXT file is created on my desktop.

Please advise the steps to find this information. Once I find this number and enter it manually, whats the steps to burn it to a DL disc in IMGBurn? Also with the disc info, which only equals 5MB, how can the 6GB of data from the original be burnt to the blank?

You can’t use ImgBurn to read original xbox360 discs, they’re copy protected.
