"Our DVD copy protection agreement with Macrovision is a vital component of our long-term plan to provide a broad range of DVD titles for the home video market," said David Partridge, Vice President of Home Video at Alliance Atlantis. "It is very important that we protect Alliance Atlantis product and the investments of our major retailers and network of licensees who sell Alliance Atlantis products worldwide."

Macrovision's DVD copy protection is designed to prevent unauthorized copying of DVD programming to VCRs without impacting the original picture. Introduced in 1997, it is the only technology of its kind that is currently available to protect against unauthorized copying from DVDs to VCRs. It has been utilized on over 75 percent of all DVDs produced worldwide -- over 180 million DVDs in total.

"We are pleased that Alliance Atlantis Communications has taken this important step in copy protecting its DVD releases," said Carol Flaherty, Vice President of Video Copy Protection at Macrovision. "With over 600 million VCRs installed worldwide, it is very easy for consumers to make high quality but unauthorized videocassette copies from the DVDs. We look forward to working with Alliance Atlantis in using DVD copy protection as an effective tool to protect its DVD revenues."
