Hulu Desktop Integration
Hulu Desktop is an experimental, Hulu Labs-devised app that gives you a 10-foot, remote-controllable interface for the TV-streaming service. Just one problem: You have no way to reach that interface from within Windows Media Center. Enter the free Hulu Desktop Integration download, which adds a Hulu Desktop icon to WMC.
One click closes WMC and opens Hulu Desktop in maximized, full-screen view. When you're done streaming, click Close to exit Hulu Desktop and return to WMC. It doesn't get much easier than that.
Note: In PC World's informal testing, this software worked on Vista as well as Windows 7. However, the developer has not tested it on Vista.
