I rendered a short test file with its project markers using Vegas 5b to a MPEG-2 format and opened it in DVD-A 2a. In DVD-A I can see the markers but I am not sure how to turn them in to chapters that I can show on a menu. Would it be better if I broke the project up, using Vegas, in to individual chapters, rendered each chapter into its own mpeg file and then inserted each mpeg file into a DVD menu?
