In my project, I have my movie and my extras both in the vts 2 titleset. I already used ifoedit to run vob extras and stripped out the main movie and kept the menu and checked that out and it seems to work fine. When I navigate the menu and go scene selections, hit play movie, etc, that all works fine. Therefore, I thought I would repeat the process this time stripping out the special feature vobs. However, my menu doesn't come up, and nothing advances to the next chapter as it should. Anyone have any idea what went wrong? P.S. I also copied the vts_01_0.bup and vts_01_0.ifo files to my new directory also, but there is no vts_01_0.vob file from the original project.
