Hi!
To put a animated wallpaper on Windows XP, there is no equivalent of Windows DreamScene, so you can convert a video as a GIF image, with Flash Professional e.g., or VLC, or even another special program to convert it. Then, go to Appearence Settings and chooseyour GIF image as a Wallpaper, and it will be animated. But, you've got to have a powerful computer (Good graphic card, and at less 512 RAM memory, like if it is about DreamScene).
