At this year's Consumer Electronics Show, Warner Home Video unveiled its Total HD disc. Developed to eliminate consumer confusion, Total HD put both HD DVD and Blu-ray content onto a single disc. While Warner originally planned to release its first Total HD titles during the second half of 2007, Video Business is reporting that they've pushed the launch back until early 2008.
Warner Home Video looks to be pushing the launch of its dual-format high-definition disc, Total HD, into 2008, from the second half of this year, as was originally planned.

Studio VP of sales and planning and operations Dan Miron said at a session during the Entertainment Supply Chain Academy conference here today that Warner will release its first titles in Total HD in early 2008.

Separately, Warner senior VP of marketing management Steve Nickerson said the studio hasn't yet set a launch date but acknowledged it's unlikely it will be in the fourth quarter.
