Audio files not compatible

Hi, I’m making my first DVD with some footage I had from my video camera. I’m using DVDit! 2.5 Professional Edition and I have a few menus and videos in the project. Everything is fine, except when I try to Build Disc... It gives me various error messages with the wave files I’m using as background music for my menus. It gives me problems like, the sampling rate, bit-rate, yadda yadda yadda.

Are there any programs that anyone uses to convert .mp3 or .wav files to the correct settings for DVD? All I know is that the sample rate or something must be 16 bits.

yes
