DVDs will look better on HDTV sets, but you won’t have the highest resolution possible. DVD video does not support HDTV, since DVD was developed before HDTV. DVD's MPEG-2 video resolutions and frame rates are similar to NTSC formats. However, DVD can use the 16:9 aspect ratio of an HDTV set. Eventually the DVD-Video format will be upgraded to an "HD-DVD" format. If you buy one of today’s DVD players, it will not be able to play HDTV discs when they come out.
