The text entry fields can hold the application name of an audio player. Often the application name is just a lower case version of the program title.
Behind application names a placeholder can be used. On invocation such placeholders get replaced with an URL (a http://..-Link) or filename for the selected radio stream.

Placeholders are introduced by a percent sign, and followed by letters. %m3u for example generates a .m3u file, which most audio players understand. Otherwise try %pls, which might even be faster because streamtuner2 doesn't have to download and preprocess it. Alternatively %srv instead gives a direct stream link.
Catch-all entries like */* or a generic audio/* entry allow to configure a default player.
"Retain deleted stations" keeps old entries, when you reload a category/genre. Shoutcast often forgets stations or throws them out. If you keep this option enabled, these entries are kept in streamtuner2. Browse down in the stations list to still see them.

Setting another temporary directory might be useful, if you want to keep the temporary .m3u cache files. They are created whenever you hit play. For archival or speed-up porposes you might want to keep them elsewhere. They don't take a lot of space.
