Warner Home Video has launched a new program that will let HD DVD fans trade in their movies for the Blu-ray version. To do so, send in the cover art to Warner's processing center, pay a small $4.95 upgrade fee (as well as $6.95/$8.95 for shipping) and in 4-5 weeks, you'll receive the Blu-ray version of the same title. While you are limited to one copy of each movie and a total of 25 titles total per household, most people will probably be more than happy to rid themselves of the defunct format. Full details can be found at Red2Blu.com.
It will be interesting to see if some of the other HD DVD backers, like Paramount and Universal , do the same thing. I don't have any Warner HD DVDs left, but I still have some from them.
