ultimate extras on non english vista ultimate editions...

someone said that you have to download the english MUI extra first so you
can get the dreamscene (video wallpaper) . Is this true?

Because I tried windows update the dreamscene was not available .. although
I think it should be... bilocker was there of course as well as the MUI for
various languages...

I set the computer to install the ENG MUI and left.... normally after it
will be installed I should see the dreamscene? right? They said you have to
download it only, you dont have to switch the interface to english to get
the other Extras...

thanks
