Some of the newer DVD progressive scan players, JVC 723 and Panasonic PR91, have a very neat feature that enables the player to reformat a 4 x 3 letterbox to 16 x 9. The picture quality definitley improves somewhat better than letterbox but not as good as a true anamorphic transfer. Nevertheless this is a great feature whether or not your HD TV accepts progressive scan on all formats. Unfortunatley the players can only reformt 4 x 3 to 16 x 9 when the DVD contains those particular instructions. I checked out all my letterbox DVD's and my JVC 723 could reformat approximatley 65%.
