Comparison of high-def DVD
By AP Wire Service
The two competing formats for high-definition DVDs are more alike than they are different.
Blu-ray and HD DVD both offer sharp, high-definition images and sound best when viewed on high-def TV screens. Both can also hold more data than a standard DVD, allowing for interactive features, games and other extras.
Both formats also require special players, which can play standard DVDs as well but not discs in the rival format.
LG Electronics Inc. and Samsung Electronics Co. have dual-format players, but they don't play all the special features. Both are priced at more than $1,000.
In terms of differences, Blu-ray can hold more data, about 50 GB, while HD DVD can hold about 30 GB.
HD DVD requires all players bearings its logo to support picture-in-picture capabilities and Internet connections that allow for downloading of trailers and other special features. Those capabilities are optional for Blu-ray players, though most players will support similar features eventually.
The biggest difference is the availability of content.
More studios, including Sony and Disney, support Blu-ray exclusively. Only Universal Pictures supports HD DVD exclusively. Warner Bros. and Paramount release films in both formats.
