I did a search, but really couldn't find anything that helped. If I overlooked it, then please point me to it. What do you do when MeGUI's AVS Script Creator can't determine the source type of the DVD? I've been using MeGUI for a while and only recently had this problem. I'm using the most up to date version of MeGUI and the video is NTSC. Do I need to somehow manually determine the source type? How do I do that? Any help would be appreciated.
