"DTS and InterVideo have worked together for many years, providing the superior audio playback of DTS technology with WinDVD," said Brian Towne, senior vice president consumer/pro division of DTS. "We're pleased that our relationship is now being expanded with DTS-HD and the InterVideo-Ulead HD DVD products. By incorporating DTS-HD technology, InterVideo-Ulead and DTS will continue to set the pace for the highest-quality audio experience on a PC."

"InterVideo and Ulead are committed to the leadership role we play in bringing HD DVD audio and video quality together for consumers," said Steve Ro, CEO and president of InterVideo. "With DTS-HD support, our customers will be able to experience the best possible surround sound while maintaining backward compatibility with existing DTS decoders and support for converting the DTS HD signal to 5.1 and stereo formats."
