Implementing Open With action

Question

I'm creating a Media Player app using Objective-C and Cocoa and I'd like the user to be able to chose a video file on Finder, right-click, select Open With and my app. I'd implemented the Open button under the File button but have no idea about how to implement the Open With thing. How can I do that?

The Info.plist CFBundleDocumentTypes entry is how the system knows what kinds of documents your app can open.
