In discussing the origin of the Chinese dragon, Walt says that dinosaurs may have coexisted with early humans. This is, of course, incorrect. Chinese beliefs about dragons were influenced by the discovery of dinosaur fossils in China, not by a race memory of living dinosaurs.
Walt pronounces Modest Mussorgsky's last name inconsistently, both with and without sounding the "g". The "g" is silent in the correct pronunciation of the name in English.
