BBC reports: "The backers of the Blu-ray high definition DVD system are predicting victory in the format wars with HD DVD. The two rival camps have divided consumers since the two incompatible systems were launched. But Blu-ray supporters are touting the decision by Warner Bros to shift allegiance as a tipping point.
HD DVD, which is backed by Microsoft and Toshiba, now has support from only Universal and Paramount among the big film studios. No-one from the HD DVD promotion group was available for comment after the organisation cancelled all press interviews at the show."
