Fixing a Flash built Icecast (Stream) Player

We have a Flash project which is an Icecast mp3 stream player (actually, its 3 variations of the same mechanism) which uses the URLRequest method to play the audio stream ([login to view URL]) this doesn't work for us because it require the stream to be reloaded every x minutes to avoid memory hog. We need a developer to switch the audio processing to netStream Progressive Download so it won't need to be reloaded every x minute, and adjust the events from the old URLRequest event to the new netStream. we have an example of a netStream player code but no idea how to implement it. Must be PROVEN experience with flash, actionscript and NetStream.
