DVD Movie Data?

Hello, im very new to this, but so far iam very impressed. My question is how do u search for the info data for your dvd movies? I ripped my movie using DVDFab in to a DVD folder then used SmartFTP to transfer my files to my Apple TV, now i got it to display my custom cover art, but how do i use IMDB to search for the movie info, cause when go into the Media section and fetch data or import it does’t find my movie, is there another setting i need to enable or something. Any help would be great, thanx
