I am considering replacing a Sony DVPNS700P DVD player (480p) with a Sony DVPNS710H/B which is advertised as "upscaling DVDs to 1080p near HD resolution via an HDMI connection." The manual of my Samsung TV refers to connecting the TV to a 480i/480p DVD player and also connecting the TV to a 480p/1080i digital TV set-top box. Will there be any visible improvement if I replace my DVD player with the Sony DVPNS710H/B model? For the record, I am not interested in replacing the TV. Thanks.
