How to discover UPCs for movies, music?

Hi--

Is there a web site and/or web service that, given a DVD/CD/cassette 
title input (or more fields to help disambiguate: artist, publisher, 
year, whatever), will return the UPC for that item? I don't necessarily 
need all the different formats/editions grouped (though I sure wouldn't 
complain if they did), just something where I can lookup the UPC.
