As Richard pointed out, ISBNs are not always used correctly.
UPC codes are traditionally 12-digit codes (and are also frequently re-used
and unreliable). And many DVDs have been assigned ISBNs because they are in
the book supply chain B&N sells quite a few DVDs, for example. So some
studios got in the habit of requesting blocks of ISBNs for assignment, for
the bookstore market.
So it's entirely possible that the DVDs have ISBNs.

Mac, I believe that those are UPC codes - barcodes - but not ISBNs. Does
anyone know for sure? Laura?
From the Bowker site:
" The ISBN identifies a book or other book-like product (such as an
audiobook) in a specific format and edition, but also the publisher."
and from their FAQ:
DVDs DVDs may not get an ISBN if they are entertainment or performance
videos. If the DVD is instructional or educational, then the DVD is eligible
for an ISBN. However, retailers vary in their requirements regarding the
type of product identification. Publishers should check with their retailers
for requirements. If the DVD is eligible for an ISBN, the ISBN is placed
near the copyright line on the packaging.
