hello, i'm new to mac and i wanted to make a copy of an original dvd, so i tried it using finder - duplicate. everything was ok, but then it showed an error with reading the disc. so i tried toast 8 titanium. but when i tried to make the copy it said the dvd is protected and decryption software is not included. i've no idea what's wrong, it's original dvd. could you help me i would be really glad
thank you
