Query: not a bargain in europe

I purchased the entire 6th season from Amazon.uk. Surprise, Surprise when I inserted the dvd I was informed that "PLAYBACK PROHIBITED BY AREA LIMITATIONS"! In other words I spent $52.00 for something that I can not use. Question: What is an area limitation? Can this only be played on DVD units manufactured in Europe?
