I just rendered an animation at 24fps at a resolution of 720x480 (16:9) and imported it into Vegas to burn in it on a DVD to be played back on a TV. The animation was originally 720x405 as it had to be widescreen but it was automatically adjusted by Vegas. The dvd after being burnt plays smooth if I play it on my PC's DVD drive just as I'd play any other movie. But when I play it on a TV using a Playstation 2 as a DVD player, the video is not smooth. Jerky or choppy - plays for 2 seconds, stops for half a second then plays again. Its like you drive your car, hit the brakes, drive again, hit the brakes...you get the idea. The audio is fine though. I also tried playing other DVD movies (discs) on that playstation2 and they played back smoothly. Here are the video settings I have in Vegas followed by the properties of the .VOB file itself on the burnt DVD. The DVD was burned at a speed of 6x.
