I have windows vista movie maker files in my desktop. But my laptop has windows 7. How can i play them in my laptop.

How do you get the letterbox (black strip on top and bottom of video) with the Windows 7 Movie Maker?

i have a visat and windows duel boot computer, and when i try to open windows vista movie maker up on windows 7(as windows 7 does not come with it), it will not work. and i do not wana have to use the crapy live moviemaker as my movies already made on vista will probly not be compatible. and its crapyer version anyway. Is there a hack or somthing of some sort? exuse my engrish as i am aussie
