indeed so.. you have to stream to a dedicated server like viastreaming.net or streamingchoice.com via your SAM or winamp etc. then enter the servers details .. eg s7.viatreaming.net 7650 on the script. then the socket can pick it up direct from them from the bot that the script is on:)
if you use shoutcast's personal stream that runs on your pc, which is not recommended unless you have a T3 connection. most domestic isps will allow you 1meg max up which on a personal stream will give you at 56kbs roughly 20 people able to connect. not to mention the strain on ram and pc resources
