DVD Lab is great, especially considering the features and the price point. However, it tends to cause video stutter even on certain standalone players (such as the ps2) even with the videos are dvd complaint video and not SVCD. When I go back and reauthor the videos with SpruceUp the stutter isn't there. Mainly I was looking for a program that can accept SVCD video without reencoding, maybe through a header patch like SpruceUP does. Any suggestions? Thanks in advance.
