Warners Bros., which effectively ended the format war when it announced sole support for Blu-ray, is letting customers swap their HD DVD titles for the Blu-ray version in its new Red2Blu program.

The studio is offering the “upgrade” program for up to 25 HD DVD titles at $4.95 a piece via Red2Blu.com.

The best part for HD DVD fans? It appears that you don’t even need to send in the disc—just the cover art sleeve for the title. So, you can keep the HD DVD disc and play it to your heart’s content.

In addition to the $4.95 upgrade price is $6.95 shipping and handling for the entire order.

Warner says you’ll receive the new Blu-ray discs within 4 to 5 weeks.
