My local public radio station recently changed its streaming "address". I have a functioning playlist with two other stations, but I cannot understand how to add the new address (yeah, I'm a noob). The link I need to add is: http://files.hawaiipublicradio.org/hpr2.pls.
In addition, I have an "old" Hawaii Public Radio address that I will need to remove from the existing radio playlist.
How do I do this?
Thanks very much..
