Help!! CDR audio on DVD player questions....

[Cane_fan]

I want to play mp3's that I download on my DVD. I use NTI CD Maker PRO to burn the cd. It converts the MP3's to WAVs on the fly. I can play these on my car cd player as well as my boom box. But I can not play them on my DVD. My DVD plays regular ( Store Bought) music cd's fine. Do I have to record these in a special format? Do I have to close the cd in some special way? I'm stuck!!! My DVD player is my only stereo in my house and I have no tunes!!!! Thanks in advance for any help.
