A 1 hr project is rendered DVD NTSC in Vegas 6d and then a project created in DVD-a3. Everything burns just fine. Then add 1 mi minute to the video length (1 hr and 1 minute) render again in V6d to the same file name, do the prepare again in DVD-A ; burn the disc and when viewed the end is cut off by 1 minute. This happened many times and had to go back and do DVD-A project from scratch.
