Looks great. As is, I can’t skip (fast forward/rewind) during the intro segment if it’s put back into the disc structure and played via the menu. It crashes unless I go back to the start.
Try this. Here is the entire BD folder structure with all files except the .Mt2s movie files (only 107 KB!). Replace all the files in your ISO and let me know if that fixes the issues.
