flip for mac not playing windows media streams

[Maurice Mines]

Whenever I try to play windows media streams, flip for mac fails to  
play the stream. What could be going wrong? I went to this site www.mediaplanetaria.com/pais.php?dest=0320 
. I also had problems playing windows media streams from other sites.

P.S. Ryan, how do you play Sirius radio streams on the website with a  
captia present
