I have a new Panasonic PT-50LC13 wide-screen LCD HDTV monitor and Denon DVM-2815 DVD player. Picture quality with the Panasonic for DishNetwork SD from my PVR-721 (routed through a JVC A/V receiver via s-video and optical audio) is excellent and I am able to use the TV aspect ratio settings to get an acceptable though slightly distorted wide-screen display of the SAT SD video. Likewise, the Denon progressive-scan DVD outputs a 480p signal directly to the TV via component video connections and produces truely stunning video and sound quality. However, with nearly all DVDs (wide-screen or not) I end up with a letterbox display format rather than a true 16:9 picture that fills the wonderful Panasonic wide-screen. There seems to be substantial variation in the degree of letterboxing among the many new and old DVDs I have played (only a couple have completely filled the 16:9 screen), and I am unable to use the TV or DVD player aspect ratio settings to achieve an acceptable non-distorted full-screen format. Is this a common issue with DVD videos and players (progressive-scan or not), and is there any way I can get a true full-screen display from DVDs?
