Ulead DVDMF:Replace audio doesn't work!?

[f96nini]

Ok, here's the scope:
I wanna replace the audio on my captured video (from camcorder) with music. I made a wav-file, which is almost as long as my video (so the last 30 seconds or so of the movie will be without sound)
I'm usin Ulead DVDMovieFactory 2.0 to author my DVD with menus and chapters. I pick the option "Replace audio" and when I preview the movie before burning it, it seems to be perfect, the original sound is replaced with the music.
But after burning it to a DVD, the music is gone and the original sound is there, dispite my efforts to replace it.
Anyone else experienced this? Do I do something wrong?
Thanks in advance!

What are the specific properties (i.e. khz, bit depth) of your .wav file?

Do they match the project settings that you've chosen in Ulead DVD MovieFactory 2?
