[How to change Dreamscene on Windows 7 with a .bat or Rainmeter Button]

Hi

i have a Question is it possible to change the Dreamscene (Video) with a klick on a Button from Rainmeter or with a .bat ?

I have win7 and the Dreamscene Activator ( http://www.blobber.org/index.php?id=18 )
works fine, but i can only change the Background Video with (Open Folder Right Mouse 'set as desktop Background) i have multiple Scenes for my Skin .

Here is a Video from my Skin (only 2 different Backgrounds) i work on 3 totally different Skins and every Skin got 2 Sub-Backgrounds.

Ps : Sorry 4 my english its 'not so good' ^^
