Basically all it means is that when you pop the DVD image onto a normal TV, it\'s be letterboxed to fit the format. On a widescreen TV, depending on the ratio, it\'ll fit perfectly into the space provided with little to no letterboxing and no loss of quality.
Wrong.  An anamorphic transfer indicates that the source image was recorded with an anamporphic lens.  The lens compresses the image in the horizontal axis (so people appear taller).  The purpose was to allow the camera to capture a widescreen image in the normal frame size on standard 35mm film stock.  When the compressed image is displayed, the projector "decompresses" it with another anamorphic lens.

Anamorphic DVDs tranfer the image content directly from the film stock without adjusting the aspect ratio.  When the DVD is displayed, the DVD player or television handles the decompression.  For example, the "full" mode on Toshiba rptvs, which would normally strech an image horizontally, instead simply corrects it in this situation.

The anamorphic quality of a motion picture has no effect on the vertical axis of the image, so it does not have any effect on the presence or absence of the black bars.  It only affects the horizontal axis.

BTW, anamorphic DVDs are very common now.  They are more common than previous transfer method, which used to encode black bars into the video signal on the DVD.

Thank God.  In the early days of DVD this was certainly not the case.

another term for anamorphic is 16 x 9 enhanced....

what it means is whatever the original aspect ratio is, it will the be same aspect ratio for 16 x 9 tv.

say, if the screen is 1.85:1.  Then it will have a slight black borders on top and bottom of the screen to fill in the 1.78:1...

if the screen is letterbox 1.85:1 for 4:3 TV (full screen tv).  It will leave a box black borders on top and bottom to make the aspect ratio looks 1.85:1 on 4:3...

same with 2.35:1 aspect ratio, if its 16 x 9 anarmorphic or 16 x 9 enhanced (or widescreen enhanced, :nut: too many terminology), it means the original aspect will be shown on the 16 x 9 hdtv...that means black borders on top and bottom of the tv (about 33% of resolutoin were thrown of because of this)....720 x 360 pixels instead of 720 x 480...

i dislike that...

but hey its better than....

4:3 anarmophic or 4:3 letterbox...

which will sacrifices more top and bottom of the screen resolution and bigger black border...

which can be as many as 720 x 240 lines...
