To confirm some of what Jonathan said... As the maintainer of a collection nearing 20,000 DVDs, I can confirm that DVDs rarely have ISBNs. When they do, it's usually educational, instructional, or musical content. I don't think I've seen a feature film DVD with an ISBN. IMDB does have UPC data for some DVDs. IIRC, searching for a UPC on IMDB takes you to a page listing the DVDs for a particular movie, rather than the main title page. The only DVDs I've seen that did not have a UPC were pre-release screeners, which I would be surprised to find in most library collections.
