BetaNews sat down with a representative from HD DVD to discuss how the Microsoft-backed format will compete with Blu-ray. Toshiba HD DVD expert Mark Knox gave a thorough explanation of the optical disc drive technology, and said that because of Blu-ray's complicated design, HD DVD will triumph in the format war.

Blu-ray's difficulties, Knox explained, begin with the technology itself, and the idea that its 50GB dual-layer capacity is superior to HD DVD's 30GB. Through the use of better codec technology, such space is not actually needed for high-definition movies. In fact, Blu-ray admitted to BetaNews that most discs won't go beyond the 25GB mark.

Although both formats are being demoed at the show, there has been much speculation about production problems in the Blu-ray camp. Knox confirmed the rumors, and said the problem involves Blu-ray's numerical aperture. In order to store more data on a disc, the laser is bent into a cone shape.
