Opening .pls files

[peasepud]

Hi, Ive searched the forum and cant seem to see this question anywhere which worries me!

I've set up everything as instructed (I believe) however when anyone attempts to follow the link that my server hosts sent me after setting up the Shoutcast server then they get a dialog box saying "you are attempting to download the file 'listen.pls' what should IE/Firefox do with this file?" and then the option of Save to disc.

I've tried google searches on .pls files and got very little joy.

The link my server hosts gave was

http://peasepud.com:8020/listen.pls

Any help would be gratefully appreciated.

Cheers

Peter
