National Geographic You Can't Lick Your Elbow

This product is made-on-demand by the manufacturer using DVD-R recordable media. Almost all DVD players can play DVD-Rs (except for some older models made before 2000) - please consult your owner's manual for formats compatible with your player. These DVD-Rs may not play on all computers or DVD player/recorders. To address this, the manufacturer recommends viewing this product on a DVD player that does not have recording capability.
