This section describes the features and use of HD DVD.
Summary
HD DVD allows users to enjoy video, concerts and other packaged content

audio and video. HD DVD also allows for the storage of long video when 
combined with the latest video compression technologies.
The storage capacity and data transfer rate of HD DVD is superior to
