“A new war has broken out as two new generations of DVD players hit stores this year. Both are targeting owners of high-definition televisions, promising to maximize their set’s capacity for razor-sharp images. One is called HD-DVD. The other is called Blu-ray. North America gets its first real look at Sony’s Blu-ray player in Las Vegas this week, with the new format hitting stores May 23. HD-DVD players go on sale at the end of this month. And soon stores will stock movies on DVD specifically formatted for one player or the other.”
