help needed on media center screensavers

Hi all..

I saw the screensavers of XP media center(aquarium, space, da vinci etc).. and they are awesome. I tried to copy them and run in xp proffessional but they didnt. If it isnt illegal, could someone please tell me if I can install those screensavers in XP Proffessional?(I've got XP Prof x64 FYI). Or can I find some answer in Google??

Thanks
