Original attempt to burn was done using 8.5 gb option but i did not manually set layer break, but from what i gather encore will prompt to set layer break manually if it cannot automatically find point,which did not happen.Project when through full build until validating media when it ejected disc with error message “this image is not an intergal of 2048 sector size (dvd error -27207)I am using Verbatim 8.5 gb 8xdvd+r printable dl, but i am not printing an image onto disc, would this have anything to do with it failing? Any suggestons Simon?
