I've be using VMS6.0 and DVDA3 for a couple of years now. So far the quality of my dvd playback has been fairly hit or miss. I've gone through a number of brands of dvd's available locally retail. The Sony discs have given me the best playback. But I would still regularly get dvd's that would freeze up and have excessive pixilation. I've reduced my burn speed and that seems to help. But the last couple of dvd's I've made have had markers placed at five minute intervels in the mpeg2 before I rendered in VMS. This appears to have made the dvd's play noticably smoother. I have generally not placed markers in the video before I rendered. Has anyone else noticed placing markers in the mpeg2 having helped the dvd play more smoothly?
