Add an extra audio track to a film

[ilmagnifico]

Hello friends
I have decrypted a DVD with DVDDecrypter.
Now I would like to burn a DVDR with the main film + original menus, but I also would like to add an additional audio track, that I have prepared in form of a WAV file (I can convert it to AC3 or whatever is needed).
I would like to add this extra audio track without losing the original subtitles and chapters of the movie.
Is it possible ? If yes, how ?
I have checked DVD Shrink 3, but despite it's a nice program, it can't do what I need.

Thank you for your help

If it's possible at all, I would say that the only reasonable solution would be IFOEDIT. Check that program out.
