Under the Radioshift menu is the "Install Players" window, as seen below.
The "Install Players" window
This window shows which third party components are installed. If any are missing or out-of-date, you can install the latest versions with just one click. Radioshift handles the rest!
Maximum Support
For maximum support, we strongly encourage you to install both third-party players. Doing so will enable you to hear tens of thousands of additional radio streams. Radioshift will install the Flip4Mac QuickTime audio component and the RealPlayer application, to provide support for the Windows Media and RealAudio audio formats.
