Cyrus: Did you view the links, dude?

Anywho, yes.. Kubrick\'s movies are an example of full-screen at work. When movies are
filmed in that format, those films should be
viewed in full-screen mode. The thing about that is, it\'s comparatively rare.
All in all, I\'d vote for "Original Aspect Ratio". Widescreen nowadays is practically standard, though.. so on average you\'re going to see a lot more movies released in the WS format.. thus I voted widescreen.
