you should also not burn at max speed - try reading at 8x and burning (this is important!) at 4x - many people have problems if a safedisc 2.9+ protected game is burned faster...
also, the read-speed depends on your drive, for example if i try to read a safedisc game in my toshiba it would take hours to get through the error-sectors, if i use my plex premium to read and set read-speed to 8x it doesn't take more than 25 seconds to pass the errors....
