DESC: Experience the hottest new DVD technology—hi-def DVD! Introduced in 2006, hi-def DVDs are completely different than the standard DVDs you're used to. The resolution of an ordinary DVD video is 480i or 480p, while an HD-DVD offers 720p or 1080i resolution—so HD-DVD is at least two times clearer than ordinary DVD! To watch DVDs in hi-def, you'll need an HDTV. Once you're hooked up, get ready to enjoy unsurpassable picture clarity and quality.
