How to add Subtitles to original DVD whitout loosing original subtitles ?

[Chainsaw_1]

Hi !

I have an original DVD with 4 subs. Norwegian, Danish , swedish , and Finnish. And i want to add in som more subs.

I have tested / try'd this guide : https://forum.videohelp.com/topic219535.html

DVD- Lab-pro let's me add 8 more subs. (do anybody know about another prog. that supports even moore ?). But when i complete my DVD and play it , the 4 original subs. (Norwegian, Danish , swedish , and Finnish) have suddenly disappeard !. The new subtitles that im adding is overwriting the original ones, but i want to keep the original ones too !. Is there any way to add more subs. To an original DVD and STILL keep the Original subs too ?
