Mysterious VTS location on DVD

I ripped dvds from a tv show to the harddrive so i dont have to keep switching discs. While doing so i discovered a VTS file video i cant locate through the DVD menu itself. Ive checked through all the menu items. It seems to be part of the bonus scenes but there seems to be no way to get to it other than physically clicking the VTS file when exploring the DVD. All the other bonus video have a link from the dvd bonus menu. Im wondering if ive overlooked something. Its the very last VTS on the disc.

Is there a way with some program that i can see what dvd menu item brings me to this specific VTS?

thanks for your time :)
