audio streaming in safari

Desperate need of some help. This has been driving me crazy for the last 3 days!

I can't stream audio from this site 1001 Albums / 1001 Albume

I though I could fix it by installing the vlc plugin which hasn't worked. I've used the website on my windows pc at work without any problem so it's something to do with the mac. Have also tried the site in firefox and opera, through vlc and quicktime and flip4mac and nothing seems to work. Can anyone help?

You can try: Perian - The swiss-army knife of QuickTime® components

Thanks - downloaded this yesterday and it hasn't done anything...do I need to change any of the settings to make it work? or change any of my web browser settings to configure with perian?
