HD-DVD and Blu-Ray are two new competing high definition DVD formats. They each provide HD video on a home video format.
Discs from each format can hold much more information than regular DVDs. This means they can hold an entire movie at HDTV resolution. Soon your DVD movies will look as good or better than the HD video television stations can provide.
HD-DVD and Blu-Ray require a special player since the discs won't play on a regular player. The good news is, the new players will play the old discs. However, the two formats are not currently compatable with each other, so you'll need a player for each. Dual format players will eventually be available, though, if the two formats can't come to a compromise.
