Using skin with stream service

Hey guys, I'm trying to skin jwplayer and use it with a stream of audio(radio feature). But this stream comes from a different server than the one I'm hosting the player, so I'm getting a crossdomain error.

The guys who host this music streaming service provided me with a link to a jwplayer (.swf) hosted on their websites. Is there anyway I can force this player to use a skin hosted in my website?

By using this code below I'm able to get a default jwplayer streaming from this service:

<embed height="21" width="260" flashvars="file=http://thirdpartystreamingservice.com:8071/;type=mp3&volume=100&bufferlength=10&autostart=false" allowscriptaccess="always" quality="high" src="http://thirdpartystreamingservice.com/radios/flashplayer/player.swf" type="application/x-shockwave-flash">

Thanks in advance!
