If you have a MAC running OSX then you already have the preferred application to stream audio, iTunes. If you're using Safari you'll see a file called listen.pls in your download window like below. If you've already told iTunes to open .pls files then iTunes will automatically open the stream.

Check your desktop.. you'll now have a listen.pls icon on it.

You can right or control-click the icon and tell your MAC what to open it with.

If you're using Firefox you'll get a window like below.

You can choose to save the file to your desktop or just open it with iTunes. iTunes will remember the stream in the library list. You may want to select the 'Do this automatically...' box before clicking OK

If you're using Internet Explorer stop using it and start using Safari or Firefox (or any other browser) Internet Explorer for the Mac has not been updated since 2001 and is no longer supported by Microsoft.

If you still have problems, send an e mail to audiohelp@ksvy.org and someone will get back to you.
