I use SDP 2.0.0 for downloading/streaming .asf files. I use RadioRipper for downloading/streaming .nsv files. I tried using Streamripper for .nsv files but it doesn't work for me.

SDP (http://all-streaming-media.com/record-video-stream/record-streaming-video-windows-media.htm#SDPReceiver) is a nice free software. It is not as powerful as WM Recorder (http://all-streaming-media.com/record-video-stream/WMRecorder-One-click-online-audio-video-stream-recorder.htm).

I think that freeware GetASFStream (http://all-streaming-media.com/record-video-stream/record-streaming-video-windows-media.htm#GetASFStream) is better than SDP, however its GUI deserves a better one.
