I'm working with DVD Architect build 67 and am encountering an error "Could not suggest a valid layer break region because the Smart Prepare data was corrupt or not accessible." I cannot find anywhere how to fix it. I've tried completely re-building the menu/dvd as well as re-encoding the videos. I've deleted the old save folder for the build and tried to prepare it beforehand (which was successful). No luck. I'm going to try to drop in the MP4s and maybe renaming the files.
Much help because these dvds need to be done by tomorrow! Thanks everyone!
