all my games after installation recieve this error when i try to play them, happens with new and older games, basically every game with some sort of copy protection.
"please insert the original disk instead of backup"

when i use nodvd patches, they work perfectly fine, but i shouldnt have to resort to such methods, anyone know why this might be happening and how to fix it?

my dvd drive is a plextor sata...could the sata cable cause this problem?
