National Geographic DVD Exclusives
For the first time ever, National Geographic presents its programming in DVD-R format. Available exclusively through this site, you can now own more of our award-winning specials and documentaries in a high-quality DVD format.
How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD Exclusives titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
