"PlayStation hackers have discovered a second way to use the console to bypass the DVD industry's strict regime. The first hack overcame the games machine's DVD regionalisation software, and now users have found out how to circumvent its DVD copy protection mechanism...."
"Sony built in the industry-standard Macrovision copy protection system to prevent just such analog to analog recordings. Macrovision's system works by modifying the output signal. On a TV, the picture will look fine, but when it passes through a recording system, the Macrovision modulation interferes with the picture signal making it unwatchable."
"The Japanese sites have published schematics of a device that they claim can strip out the Macrovision signal. The box essentially converts the RGB signal to an NTSC (the US analog TV standard) composite signal, but appears to negate the effect of Macrovision too."
