Hello, I created a blu-ray disk of a single title with multiple chapter markers in DVDA 7. The markers are all linked to separate links in the sub-menu pages, and those links work fine. But while the movie is playing, hitting Prev or Next chapter does not work. (I have read many posts about this, but it seems most people have separate titles. This is one title with multiple chapter markers, imported from Vegas 14.) Any ideas why these buttons are not working, and how to fix it? Fast Fwd works, but this is a movie of a dance recital, and the dancers will want to skip ahead to their dance while playing, rather than returning to the submenus. Thanks!
