c|net - Consumers wary of buying new high-definition DVD players because of a technology war reminiscent of the days of Betamax versus VHS will soon have a new kind of DVD that might make the decision less daunting. Warner Bros., which helped popularize the DVD more than a decade ago, plans to announce next week a single videodisc that can play films and television programs in both Blu-ray and HD DVD, the rival DVD technologies. Warner Bros., a division of Time Warner, plans to formally announce the new disc, which it is calling a Total HD disc, at the Consumer Electronics Show in Las Vegas on Tuesday. Two rival camps introduced high-definition DVD players last year: a consortium called Blu-ray, backed by Sony and others, and a group called HD DVD, backed by Toshiba and Microsoft. Retail and media executives say this clash of corporate titans and their incompatible machines has left some consumers bewildered and has slowed the introduction of what is intended to be the next great thing in home entertainment.
