<form name='aspnetForm' method='post' action='Default.aspx' id='aspnetForm'> <form></form>. // FLASH PLAYER CODE </form>
For security reasons, a Macromedia Flash movie playing in a web browser is not allowed to access data that resides outside the exact web domain from which the SWF originated.
However, these files can be loaded and accessed by the MP3 Player correctly if a crossdomain.xml file is placed on that domain.
This way the MP3 Player knows it is allowed to load these files.
MP3 files loaded from another domain without a crossdomain.xml file can't show spectrum visualizations because of this reason.
In this case only the 'peak' visualization works.
To fix this problem, use a crossdomain.xml file.
