I recently made a DVD with Encore and burned the finished product to a disc using the same computer I created the project on (I actually created the DVD files and made the disc from that). The DVD worked exactly as it was suppose to. I burned another DVD from the same files (off of a portable hard drive) using a different computer and the menus/highlights were off. I went back and was able to burn a perfect DVD on the original computer using the exact same files. Anyone ever see this problem before? Does anyone know why this happened?
