Warner Bros has made good on its promise to deliver a hybrid HD DVD Blu-ray disc.

The Total Hi Def disc plays HD DVD on one side, and Blu-ray on the other.

The company is marketing it as a winning solution for both consumers, confused about the differing formats, and retailers, who can reduce the shelf space required to carry two or three versions of the same film.

The disc won't be available until the second half of the year, and Warner has yet to make any announcements about release titles.

LG at CES unveiled its solution to format wars, its HD DVD Blu-ray player, while Toshiba announced it's developed a 51GB triple-layer HD DVD.

“The Total Hi Def disc is about giving consumers complete choice, providing creators and artists the greatest possible distribution of their work, and helping retailers thrive in the marketplace”, said Kevin Tsujihara, President of Warner Bros Home Entertainment Group.
