Microsoft CD copy protection advances
April 23, 2003
The update attempts to simulate most of what people are doing with CDs on their computers. Content owners such as record labels would be able to set the "usage rules" on the Microsoft Windows Media files included on a Macrovision-protected CD, allowing a specified numbers of CD burns and transfers to portable devices, for example.
Macrovision hopes that its new technology, called CDS-300, will make CD copy protection more palatable to consumers who have grown used to the restrictions on music purchased from online song stores.
"Before, you had the 'second session' that was bolted to the disc," said Adam Sexton, Macrovision's vice president of marketing. "We're pleased we can now deliver the same functions and can go 'mano a mano' with the online services."
The copy-protection company's previous software blocked people from making copies of CDs by rendering the music files invisible to most computers. However, the protected CDs also held additional versions of the songs in the Microsoft Windows Media format, which could be played on PCs. This separate set of music files, called a "second session," could not be transferred off the CD or put on portable devices, however.
That restriction stood in poor contrast to songs purchased from Apple Computer's iTunes, Napster or other services, which can be burned to a CD, used on several computers, or transferred to a portable device. They also include some anticopying restrictions, however.
Loosening the restrictions on copy-protected CDs may represent a step forward for digital rights management, but the company's technology is likely to remain controversial with consumers.
Macrovision's software and rival products from companies, such as SunnComm Technologies, are intended to curb unregulated CD copying and the practice of "ripping" unprotected MP3s, which can be distributed through file-swapping services or by other digital means.
Record labels are eager to bring both activities under control. But they're also leery of a backlash from consumers, who are used to copying and ripping CDs and who might view the new CD protections as an unfair constraint. Several lawsuits have already been filed in the United States and the United Kingdom over CD copy-protection techniques.
To date, CD copy protection has not been widely distributed in the United States. Record labels there are looking for even greater protections, such as preventing burned CDs from being copied additional times, according to Sexton.
The new Macrovision technology is being tested in production plants in Europe, and it is not likely to find its way to a commercial release for at least another quarter. It will be available for record labels to use around the world.

All you need is a program actually capable of reading each track of each session manually, with the ablity to rip each track individually, or as a group.
Also, all we need to get around THIS system is get something to rout the raw audio PCM output generated form the media file, the supposed WMA or such with protection onto the harddrive, instead of the speakers, or better yet, hex edit out the header with the protection information, and there we go.
The only protection against copying is not releasing the file in the first place. At all.
