SDL_mixer/MP3 question

While using SDL_mixer 1.2.5 on the Windows platform, I am getting Module
Not Found when attempting to load MP3 files. It works fine with the WAV
files. Any thoughts? I tried downloading the library and the smpeg
library sources and compiling them, but they would not compile.

I am using the binary version of SDL_mixer 1.2.5, Windows 2000 Pro,
Visual Studio .Net 2003, and SDL 1.2.7.

Thanks, Jason
