My Method for authoring is to create the source DVD Mpeg in TMPEGEnc and then creating a title set of that MPeg 2 file with SpruceUP, however this has yet to work. I have struggled a while to find a way to do something that should be relatively simple but it still doesnt work. Whenever my computer spits out those VOB files, no matter what I try, they turn out bad. You play the VOB video and it speeds up at parts and jerks around. I looked for a darn long time to see if anyone had the same topic of question but I could not find anything. It seems to happen with multiple programs on my computer and even when I tried it on my roomates computer. Anyone know why. -Aaron
