Create the CFFL file, use REMPEG2 to change the video quality. Then open IFOedit 0.6, open the ifo file associated with the movie (the same title set of the vobs you rmpged earlier), and you can remux, strip streams and strip ID's at the same time. You will end up with a group of VOBs with stripped audio (if you stripped audio streams) and with the video remuxed. That's all! You don't have to use Ifoedit 0.9 for anything, except, of course, if you use this version to create your CFFL automatically. All other operations can be done with 0.6 You could also strip only streams with Ifoedit 0.92...it is only when remuxing video that the movie results with slight pauses (mostly after chapter points).
