call me the ps2 detective rce its the only logical way for them to combat dvd-r media using the write strategy id's its more or less a type of safedisc protection but built in the hardware rather than software "disc"
"Part of SafeDisc is to check to see if there is any ATPI info and if there is then
it will give you the error of "wrong cd place the orginal in the cdrom"
another way i suppose is to read the power levels needed to calibrate the lense for reading diffrent media and use this as protection for dvd-r as pressed and dvd-r have a diffrent calibration both ways would still allow pressed hongkong silvers to run fine on a v8.
The power level's would be normal with it being pressed like an original so this would pass any check, also no id tag would be present either again with it being pressed disc.
other than that i cant see any other way to protect against dvd-r media.
also a few people i have talked to have pointed me in this direction aswell
