MediaMax CD-3 is a software package created by SunnComm which was sold as a form of copy protection for compact discs. It was used by the record label RCA Records/BMG, and targets both Microsoft Windows and Mac OS X. Elected officials and computer security experts regard the software as a form of malware since its purpose is to intercept and inhibit normal computer operation without the user's authorization. MediaMax received media attention in late 2005 in fallout from the Sony XCP copy protection scandal. MediaMax is a second-generation system meant to address the problems of earlier copy-preventing schemes, where many types of playback devices had difficulty reading discs in normal use. MediaMax was first used on Anthony Hamilton's Comin' From Where I'm From in the United States; the first US No. 1 CD to use it was Velvet Revolver's Contraband. (The European release of the Velvet Revolver album used Macrovision CDS-200 and the Japanese is without copy protection.) Identifying MediaMax discs Some BMG discs using the scheme have a label affixed to the front that states: This CD is protected against unauthorized duplication. It is designed to play on standard playback devices and an appropriately configured computer (see system requirements on back). If you have questions or concerns visit www.sunncomm.com/support/bmg A section on the back of some packages states, in part: This CD is enhanced with MediaMax software. Windows compatible instructions: Insert disc into CD-ROM drive. Software will automatically install. If it doesn't, click on "LaunchCd.exe." MacOS instructions: Insert disc into CD-ROM drive. Click on "Start." Usage of the CD on your computer requires your acceptance of the End User License Agreement and installation of specific software contained on the CD. Method of operation The music on a MediaMax disc is contained in tracks as on a regular compact disc, while the DRM software is present in an additional data track. Therefore, such discs work with almost any CD playback device. Copy restriction is only enforced by the software on the disc: If the software is not installed, disc duplication is not inhibited. On computers running Microsoft Windows, the typical installation vector is the AutoRun feature of the operating system. When a MediaMax disc is inserted into a Windows PC with AutoRun enabled, software on the disc called LaunchCd.exe installs a device driver that inhibits the ability of other software to directly read data from audio discs in the CD-ROM
