Neil, things got busy at work after you posted originally, so I didn't get a chance to try this until today. And I only had time for a quick test. The program certainly gives me a lot more options for layer breaks than Encore. But when I play the resulting .iso file using VSO Player (burning dual layer DVDs takes forever on my system), it seems that the menus have disappeared. So I need more time to dig into how this program works. But I can already tell that this will be very useful for future dual layer DVD projects.
