Problem with radio player

Hi, Ive got a problem with the radio streaming on your theme “MusicPlay 2.0”
My problem is that I can’t make work correctly the radio streaming with this address:

http://onair20.xdevel.com:8154/

I’ve try to put:

http://onair20.xdevel.com:8154/
or
http://onair20.xdevel.com:8154/;stream/1

and alsto try to put the address directly in the file: radio-player.php
mp3:”http://onair20.xdevel.com:8154/;stream/1″

But still don’t work!
I’ve also try to put the link into iTunes (http://onair20.xdevel.com:8154/listen.pls
) and all work fine… the streaming is UP
when I’ve tried to make it work with another address: http://onair20.xdevel.com:8120/;stream/1
(8120 instead 8154) also work fine!
can you please help me to fix the problem?
Thank you!
