...that the DVDs you saw in Thailand were *pirated* ones -- illegal copies pressed locally, without paying *anything* to the copyright holders.
What I'm talking about is the "official" price of the "real" stuff, the DVDs that the American media mega-corps sell in Europe (and, I guess, Thailand; although they probably don't sell a *lot* of 'em there, with competition from the pirates...)
And thanks for correcting the spelling -- though in the mean time, I suggested an alternative interpretation elsewhere. :-)
