WMS MP3 Media Parser
The MP3 Media Parser plug-in allows Windows Media Services to stream MP3-encoded audio files.
Windows Media Services cannot use the intelligent streaming feature to stream MP3-formatted files. In addition, Windows Media Services cannot stream multiple-bit-rate (MBR) MP3 files. If the MP3 file was encoded by using a multiple bit rate, it will not play back as expected when it is streamed from a Windows Media server.
