What is the difference between HD-DVD and Blu-Ray DVDs?
High-definition DVD is a generic term for the next generation of DVD technology, which can burn more information onto the same size disc as your current CDs and DVDs. Like a DVD, it can be used for either video or computer data. But you’ll need new hardware to play a hi-def disc on either your TV or your PC. There are two competing formats of hi-def DVD: Blu-ray and HD-DVD. Much like VHS and BetaMax, they are incompatible, and eventually only one standard is likely to “win,” although both theoretically output video at the same quality and resolution. The jury’s out on which will be the victor: Momentum swings from one side to the other every couple of months.
