Dou you know that your desktop background or your wallpaper can have action, yah, you can do that with Windows DreamScene, but only on Windows Vista Ultimate. When you download this Ultimate Extra, you can select a video for your desktop background the same way you select a stationary picture. You can choose one of the high-quality looping videos that we’ve included, or use a video from a company that produces content for DreamScene. You can even use your own video as a background.
The Windows DreamScene respects your power settings and pauses the video to conserve battery power.
-Windows DreamScene supports only .mpeg and .wmv video file formats.
-Windows DreamScene video support requires a graphics card that supports Windows Aero™.
