As far as I can decipher, after hours of searching - you must be a computer programmer to actually use this program.
I tried adding a URL from several different types of sources (.asx, php, .pls), but in each case absolutely nothing happened. The program did not appear to attempt to connect or play the stream.
If some step by step instructions were available (for the layman), perhaps this program could actually work?
I'm using Mac OS 10.7.1.
