Windows DreamScene is a utility that allows videos to be used as animated desktop wallpapers. It is one of the Windows Vista Ultimate Extras (you can get it from Windows Update if you have Windows Vista Ultimate). When you maximize a window or play full screen games, videos pause to save the cpu and graphics card power.

How to install DreamScene
Open Windows Update and Check for Updates. Under the Ultimate Extras, check the Windows Dreamscene option and hit Install. After rebooting your PC, right click on the desktop and select Personalize. Click Desktop Wallpaper, browse and select the video and hit OK.
