To download mms/rtsp, you need to know the url(the file name and server address) of you want to download. Unfortunately, some links to streaming audio and video that you come across on the web are hidden behind javascript or activex scripts. Because of this, it is sometimes very difficult to figure out the actual urls that correspond to the streams being played. URL Helper provide a one-step solution to finding the URLs for all streams. It does this by searching files and watching network traffic and identifying potential urls.
