The player stops randomly on Windows XP

Hi,

we use Audio module with podcast feature on our webradio website: http://www.lacompagniedesondes.fr/

It works well, but we have bug returns only on windows XP system (the browser is Firefox). The bug is hard to reproduce, because we don't have the problem on Macs, or 2000 or Vista. It seems the player breaks after 30 mins or 40 mins, it's random. No problem, when we download the file.

Someone knows something about this? Nothing on the issue queue, I think.
