Apple released a supplemental update to fix issues with gatekeeper - you might be affected. Please check whether your OS is up to date. When clicking on the version string in the "About This Mac" dialog accessible through the Apple menu, you should see "Build 11G63".
If this doesn't help, make sure that you correctly copied VLC.app to the Applications folder on your hard drive (probably called "Macintosh HD").
