I'm trying to make a backup of my navigation dvd that my car uses, but the disc I made isn't recognized. It is set to DVD-ROM Booktype, but I believe my fault was not setting the Layer Break correctly. ImgBurn just did it's own layer break and did 50% on Layer 1 and 50% on layer two. When I go back and look at my Original Navigation Disc it says 61.45% and 38.55% for the layer breaks.

When I create the Layer Break file for this image, should it be 1901968?
