HP had demanded that Blu-ray adopt Mandatory Managed Copy completely, as well as iHD, which would provide new interface features for the format. The Blu-ray group however declined to use iHD, and are backing a Java-based menu system instead. iHD is slated to be part of Microsoft's newest operating system, Windows Vista, and it is already supported by HD DVD.
It seems now that the movie studios are going for Blu-ray Disc for its strong copy protection whereas many tech companies are leaning towards HD DVD because of the consumer friend features it supports. Bill Gates recently called Blu-ray's copy protection, anti-consumer. "The inconvenience is that the studios got too much protection at the expense of consumers and it won't work well on PCs," Gates explained.
