I exported a video that is 1 hour and 32 minutes in length from Premiere Pro 1.5 and burned it to DVD in Encore. When I play it back on the computer I burned it with, it plays in slow motion. When I play it on my work laptop, it plays fine in parts and stutters significantly in parts. This is the longest video I've burned to DVD so I dont know if that might be the problem. I used all the preset settings that are there when you create a new project in Encore. I used a Magnavox DVD+R. Ideas?
