I live in a multilingual home...We have four different languages represented and not everyone understands all the languages well. I would like to add an extra language subtitle to an existing DVD. The DVD already has two subtitle languages that I would like to keep, but would like to add a third. I have the script in the third language, but do not know how to get it from this point onto a finished DVD. Also if possible I would like to keep the menus the same except for under subtitle having a third language option. Any help would be greatly appreciated.
