The World Wrestling Federation is currently undergoing numerous technical changes in preparation for high definition television and is also increasing its interest in the DVD format. Today Macrovision Corporation announced that World Wrestling Federation Entertainment, Inc. has signed an agreement to copy protect 100 percent of its WWF Home Video DVD titles.

Macrovision’s DVD copy protection is designed to prevent unauthorized copying of DVD programming to VCRs without impacting the original picture. It is now used on most DVDs being released and is the only technology of its kind that is currently available to protect against unauthorized copying from DVDs to VCRs.
