WinAMP 3 can't play streaming audio on XP

[mweiss]

I have several computers. Most are running Win 2K and the older WinAMP 1.82 player. These have no trouble playing a Shoutcast stream embedded as a link on a web browser, such as http://24.151.63.87:8000/listen.pls .

However, on my new XP Home (Service Pack 1 installed), I have WinAMP 3 there and it will load when I click on a Shoutcast link like the one above, but it just sits there and does nothing. Sometimes it displays the URL in the title window and that's all. Pushing PLAY button does not start the stream playback.

Any ideas what might be misconfigured in WinAMP or XP?
