Voice and music tracks

[Hamel]

I made a 40 minutes movies for the 50th wedding anniversary of my parents. So, when I create disc, this message appears : "The process got some problems." I checked the files of my project and it seems to me that all is ok. However, in the case of, I changed all 24 bits WAV files to 16 bits (voice and music track). After tthis change, the message did not reappear.
It is possible that VideoStudio have some problems to recognize the audio in 24 bits format in the process of creation of the disc ?

Thank you very much.
