(quote from help file)
To export a playlist
Click Media Library, and then expand My Playlists to display the playlists that you have created.
Click the playlist you want to export.
On the File menu, click Export Playlist to File.
Select the folder you want to save the file to, in File name, enter a name for the file, and then click Save.

Ok but it only allows me to export to .asx .wax or .wvx file types. I want an .m3u playlist. If I simply change the file type extention the file won't work as m3u cuz it's different text format for listing and such.

Question then is: How do I export to an .m3u playlist file from Windows Media Player?

Thank you.
