This time I'll bold and underline the important parts for you, ALA Spark Notes.
Obama created a minor diplo-mess when British Prime Minister Gordon Brown came to the U.S. for a visit. Obama's historic Oval Office desk, a gift from Queen Victoria to Rutherford Hayes, is made from the timbers of the HMS Resolute. Brown proudly presented Obama with a pencil holder carved from its antislavery sister ship, the HMS Gannet. Classy! Obama lamely reciprocated with a DVD set of Hollywood movies, including "Psycho." When Brown got back home, he discovered [the DVDs] didn't work in his European player.
Brown's gift had deep historical signficance and recognized the vitality and legitimacy of the USA's past history.
Obama gave some (admittingly classic) American DVDs that did not make a similar gesture to the UK, and ironically could not even be watched by Brown.
Probably not a big deal to most Americans (as you demonstrate), because as iamzack (well, sort of) says we don't understand the history of foreign relations/foreign countries let alone our own history, and would rather be entertained by shiny things on a screen. I don't claim to be above this, seeing as I'm on a videogame modding forum, and all that.
