Elisa not only looks and works great but it packs a surprise, it also works on Windows systems. Since Elisa runs on top of the Gstreamer multimedia framework you can run it on your Windows system. That means you don’t have to shell out $200 to upgrade to the Media Center Version of Windows XP.
Ain’t open source great?
