No. Windows Media Player 9 Series can play files in a wide variety of digital media file formats, but Windows Media Services 9 Series cannot stream all of those files. In certain cases, you may need to convert digital media files into a compatible format before you can stream them.
Servers running Windows Media Services 9 Series can stream files that are in the Microsoft Windows Media Audio (WMA), Windows Media Video (WMV), Advanced Systems Format (ASF), and Motion Picture Experts Group (MPEG)-1 Layer 3 (MP3) formats. However, Windows Media Services cannot use the intelligent streaming feature to stream files in MP3 format.
You can use a Windows Media server to stream files in other digital media file formats if the appropriate media parser plug-in is enabled. A media parser plug-in translates the information contained within the file to a format that can be used by the Windows Media server and Windows Media Player. To find out whether a media parser plug-in is available for the format you want to stream, contact the digital media file format developer.0
