Yes well the tutorials were exported at at a much higher resolution and 640 by 480 maintains the aspect ratio so it doesnt stretch…Im using PC and Encore CS3….These DVD’s need to be played at a high quality…and the regular DVD doesnt not cut it with the quality on the PC….A mjority of these DVD’s will be played on a computer as they are for computer artists….If i can find out how i can get this DVD to a DVD ROM so it will play the same way that would be great..
