none: Why don't we all agree on a "standard" GOUT?
ReJig can demux the video from a DVD if provided with an IFO. It stores the entire video stream in an m2v container. Yes, the entire movie.
I have created an m2v and accompanying d2v using ReJig and DGIndex, respectively.
Would you be interested in working together on this? If so, I can provide you with my m2v and d2v to work with as a base.
My m2v/d2v matches up with Darth Mallwalker's IP reel frame numbers, FWIW.
