Wahoo! I found the solution to the subtitle problem: Convert the srt from 23.976fps to 24fps in Jubler, then use Lemony to create the BDN. Edit the XML to set the framerate back to 23.976 and import as non-drop. Then subs remain in sync to the end. Rinse and repeat for all languages. We’re back in business people!
Throw it in a pot, add some broth, a potato… baby you got a stew going!
