Getting Started

I installed dvdrip via yum on a fedora system  Things seemed to go fine.  I put a DVD disc in my drive.  Started dvdrip.  Created a new project.  Everything seemed to go fine, but there's no "Start" button.  There doesn't seem to be anything else to do, but my DVD isn't being ripped.  Nothing's happening.

So, I must be missing something obvious.  What next?  What do I have to do to start the DVD rip?  Also, is there a "Getting Started" page?  I looked at the FAQ on the website, and those questions seem to be for users who already got further than me.
