Macrovision Corporation (Nasdaq: MVSN), the leading developer and supplier of digital rights management ("DRM") products, today announced that it has integrated its latest DRM solution (MacroSafe™) with InterVideo's WinDVD, the world's most popular DVD player. The two companies will also join in co-marketing efforts to promote this secure solution to the video on demand market.

MacroSafe is a complete end-to-end digital rights management solution for the secure distribution and consumption of high value video, audio and other multimedia content to PCs, personal video recorders and set-top boxes.

InterVideo's WinDVD 4 is the most sophisticated DVD-playing software on the market and is bundled with 9 of the top 10 PC makers in the world including Dell, HP, Sony, IBM and others. In addition to playing DVDs, WinDVD can also play MPEG-1, MPEG-2 and DivX™ content from files, such as those that might be downloaded from an Internet movie rental site.

The integration of the MacroSafe client with the WinDVD player enables the combined solution to:

• Recognize content that has been encrypted and protected using the MacroSafe system
• Determine if the user has the right to view the content
• Enable easy playback of the content, if appropriate
• Inhibit unauthorized peer-to-peer file sharing
