I am having the same problem as the person who made the post on this page only I use a PC. I am also trying to burn a dual-layer disc in Adobe Encore CS3 on a PC. I have a DVD +R DL disc and my PC definitely burns DL discs. My project is over 4 GB so I have to use DL. When I try to burn my disc it starts to build and then gives an error that says I need to specify a layer break. I have tried selecting both Automatic and manual, but I get the error every time! How do I specify the break? It also gives the same error when I try to burn an image file.
