   SDL_Mixer problems.
  The problem is with music.1. I can't play wavs, it just crashes.2. Oggs play all right the first time, but after it loops it starts distorting badly, with a lot of noise. Tryed many levels of compression and with different softwares and still the same.3. mp3 works ok, but i cant use those in a commercial game right?Help please :S   
  When I used SDL_Mixer for the first time this tutorial  helped me a lot.Hope it might answer to your problems.
