Fancy a wee DRM?

WHILE WE'RE ALL gazing at what Microsoft's up to in the CD arena, Macrovision has been quietly filing copy protection patents for protecting content.
It's latest is a Japanese patent – 3,405,980 – which stops a PC from recognising Red Book audio content when a protected music CD gets inserted in a PC.
Macrovision's patent protects, if that's the right word, the PC from making audio copies.
Macrovision said it's the basis for its CDS product line which it claims counters the threat CD recordable drives pose to the music business.
When the technology is coupled to Windows Media DRM, it lets the record companies make music CDs that play on old fashioned stereos but also "second session" files for storing on a PC. µ
* Sorry Macromedia, originally had you lot in the title.
