need my station to play on macs

[dwayne00]

I have my station up and running perfect. But I visited a friend today with a mac and we tried to play my station from my site and it couldn't. I have the code set to play .asx files I know this is for windows media but is there some way where i can have my station to open on windows and macs both? Is there a certain way to code it to open the main player on macs in order to play the station as well as windows?
