The end result of their testing, Bell told me, was the assessment that HD DVD is simply a "very consistent, stable specification." He said that all HD DVD players have had to meet the same specifications and that, in his estimation, HD DVD's specifications are more suited for the current market. Blu-ray, on the other hand, has been a moving target, and this could end up hurting early adopters who might be chagrined to find significant differences between players.
For instance, Bell expressed appreciation for the fact that all HD DVD players support a minimum standard of connectivity and interactive features, something that is not true for Blu-ray. He also noted that the moving feature set on Blu-ray players meant that programming for interactive content could not be done in a way that was guaranteed to work with all Blu-ray players. A feature present on one might be absent in another (compare the feature set of
300 on HD DVD versus that of Blu-ray). Praising Microsoft's HDi interactivity platform, Bell said it was "very full, with a very wide scope," yet it was easy to work with and would provide a consistent experience regardless of HD DVD player used.
Bell also considers HD DVD's heritage to be an asset; coming out of the DVD Forum, HD DVD was designed to be the true successor to DVD, and Bell noted that HD DVD was indeed less expensive to manufacture using already existing manufacturing techniques.
