SSL Certificate and using iTunes or VLC under Mac OS

I'd like to use iTunes or another music player under Mac OS. But they won't connect to my HTTPS Subsonic server, and I think the problem is that I don't have my own certificate. Is that even correct? It works with Winamp under Windows. That has never had a cert problem. Here is the info in Getting Started at subsonic.org
I completely don't understand any of this. I've generated a cert for use with FileZilla FTP Server. Can I use that?
I've googled this up and down, but haven't found exactly how to get this working under Windows. Can someone please point me in the right direction? Thanks for any info.
Note that Subsonic uses a self-signed https certificate by default. This provides encryption but not proper authentication. To use your own certificate you must put it in a Java keystore, then specify the following Java system properties: subsonic.ssl.keystore (path to an alternate SSL keystore), and subsonic.ssl.password (password of the alternate SSL keystore). On Windows, you can set these system properties in C:\Program Files (x86)\Subsonic\subsonic-service.exe.vmoptions.
