Looking for who said what in the sound world? Well there is no better place to find every audio related press release than 3DsoundSurge.!

The Avid Xpress DV on IBM IntelliStation and DVDit! combination enables Avid Xpress DV users to publish their films, videos, presentations, training, or any other multimedia content on the popular DVD format.

DVDit! provides a simple, yet powerful interface for publishing Avid Xpress DV video projects on DVD. DVDit! converts video and audio data directly from an Avid Xpress DV workstation into DVD-compliant video streams. DVDit! allows users to build their own menus, add graphics and buttons, emulate a DVD player, and format a DVD volume which can then be recorded to DVD-R for playback on set-top players or DVD-equipped PCs.

Short-duration projects can be recorded to CD-R or CD-RW and played on DVD-equipped PCs.

``DVD has become a universal format, and there is very strong interest among our users to create DVD-based interactive content,'' said Patrick Dumas, Avid's Vice President of Worldwide Product Marketing. ``Sonic's revolutionary DVDit! is a great addition to our Avid Xpress DV product line because it allows our users to publish their high-quality video and audio content onto DVD. Sonic's DVDit! is the enabling application for the DVD publishing revolution.''

``With the installed base of DVD set-top and DVD-equipped PCs expected to reach 50 million units by the end of 1999, DVD is now the format of choice for publishing high-quality digital video,'' said Christopher Kryzan, Senior Vice President of Marketing and Engineering at Sonic Solutions.

``Combining DVDit! with Avid's industry-leading line of Windows NT video editing workstations gives video professionals the power to edit their material in the familiar Avid production environment and then publish their work digitally on DVD.''
