problems loading .pls with mozilla

[global_groove6]

I have this problem with anyone clicking on any of the tune-in .pls links on my site using a mozzila browser:

http://www.planetsoulnetwork.com

Instead of winamp playing the stream they are getting this in their browser:

[Playlist]
File1=http://stream01.prolocation.net:9500
Length1=-1
File2=:http://stream02.prolocation.net:9500
Length2=-1
Numberofentries=2
Version=2

anyone know where the problem is? Is it my html page or is it a problem at the server level? thanks!
