![]() ![]() The purpose for this is so that people with 16:9 sets do not have to change the mode on their TV when switching between the feature and the suppliments. In those cases, they horizontally letterbox it to the correct ratio. What you are running into is a trend of going ahead and anamorphically compressing the supplements on anamorphic widescreen discs, even if the supplements were primarily 1.33:1 footage. Since the image was horizontally compressed, there is no additional loss of resolution compared to if the image had simply been letterboxed uncompressed. ![]() When the DVD player is set to think you have a regular 4:3 set, it digitally decompresses the anamorphic image before sending the signal to the analog outputs for display on the TV. Even with wider images (such as 2.35:1 scope films), the loss of resolution is less than if the image was letterboxed uncompressed. Since the image is horizontally compressed, there is no loss of vertical resolution when placing the 16:9 image onto the normally 4:3 video signal. The reason for this feature is that it results in a higher-resolution image on a 16:9 monitor. This is the purpose of the setting on the DVD player's configuration menu to tell the player what aspect ratio your television is. That image is expanded back to its full width either by the DVD player or the television. This means that a 16:9 image is horizontally compressed into the standard 4:3 NTSC video image. One of the capabilities of the DVD format is what is referred to as "anamorphic" mode. I suspect you have a setting wrong on either your player or the TV.
