MediaMax CD-3



MediaMax CD-3 is a type of copy protection for compact discs that is sold by SunnComm and used by the record label RCA Records/BMG. It 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 (album)''. (The European release of the Velvet Revolver album used Macrovision CDS-200 and the Japanese is without copy protection.) 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 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." Mac OS 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. The system uses a normal compact disc format containing an additional data track, so CDs using the MediaMax scheme will work with almost any CD playback device. The "protection" comes from the installation of additional software, and the requirement that the user accept an end user license agreement (EULA). The fatal flaw in the MediaMax system is that if the software isn't installed, or if it is disabled, discs can be duplicated without any trouble. On computers running Microsoft Windows, the copy protection scheme makes use of the autorun feature of the operating system to a run program named LaunchCd.exe, which installs a device driver that inhibits the ability of other software to directly read data from the disc. Many users disable the autorun feature, since it is a potential (but rarely used) vector for computer viruses and spyware, and therefore do not run the MediaMax software. People who leave it enabled can easily prevent the software from loading by holding down the Shift key while inserting the disc. It is unclear if the version of the software written for Mac OS has the same ability or not. There is no version for Linux or any other operating system. Because of this, the system is largely considered to be ineffectual. However, anyone using a MediaMax disc without the software is theoretically in breach of contract, as they have not accepted the EULA. People using Linux and other alternative operating systems may effectively be in a sort of legal limbo, though it may be possible to skirt that problem by using an emulator such as Wine (software) to load the software and accept the EULA. When the MediaMax software is functioning as designed, it allows copying to a certain extent. Compressed audio is stored on the disc in Windows Media Audio (WMA) files. The following activities are allowed: * Copying tracks to the hard drive for playback without the original CD * Burning tracks to CDs up to 3 times * Sharing the songs, by emailing links to digital rights management-controlled files that expire after 10 days * Downloading tracks to DRM-enabled portable players == External links == * [http://www.sunncomm.com/support/bmg SunnComm Customer Care: Frequently Asked Questions] * [http://www.cs.princeton.edu/~jhalderm/cd3/ Analysis of the MediaMax CD3 Copy-Prevention System] Digital rights management
