You guys are seriously over complicating the purpose of anamorphic video.
Unlike other video formats (divx, for example) which allows for user specified image dimensions, DVD is a fixed 4:3 ratio with pixel dimensions of 720x480 (regular TV pixels aren't square).
"Anamorphic" means that a 16:9 frame (or other "wide screen" ratio) is stretched vertically (not horizontally as previously stated) to 16:12 (thus becoming 4:3). This makes use of the entire 4:3 video space on a DVD, giving 33% greater vertical resolution than encoding it with black bars. To display it properly, something has to squeeze it back to it's original ratio. Most people will use their DVD players to do this, people with TV's capable of anamorphic squeeze (ie my Wega) compress the scan range vertically to use the entire vertical scan range to draw the image rather than wasting scan lines on the black boxes.
That's all it is, putting more 16:9 picture information into the 4:3 shaped box that is DVD.

I said "squeezed horizontally." You said stretched vertically. What's the diff?
And I explained it in fewer words, PLUS I provided pics.
