Amazon's Definition of "World Cinema"

I'm browsing the DVD section on Amazon.co.uk, looking for something new and unfamiliar to add to my rental list. I click on "Browse Categories" and then click on the "World Cinema" hyperlink in the middle of my screen (admittedly not realising that it lies within a "Box Sets" subheading).  The first screen of results that I'm presented with includes:

• ER Season 8
• Frasier Season 5
• Friends - Complete Series 1 - 10
• West Wing Season 7
• Twin Peaks Season 2
• Midsomer Murders Season 2
• Alias Season 3

What kind of strange definition of "world cinema" is this?!
