That doesn't sound right. You're saying the website contains nothing but one mp3 file? And the root directory of the web site redirects to that file? I think you're missing something in the URL. I would think it should at least look like http://17x.xxx.17x.5x:8000/yyyy.mp3.
If you enter that URL in your browser, what happens? Do you go to a web site or does it just start playing an mp3 file? If the former, then your URL is incomplete.
Mark, that's normal for a SHOUTcast stream. In this instance, the url is pointing to a SHOUTcast server, not a website.
newchannel, based on the XML posted, it looks like you might be trying to use the video format for your content. Are you parsing that and passing it to an roAudioPlayer component, or are you trying to use the same code you use for video? The latter is unlikely to work.
