I have tried to back up Tony Hawk's Underground over and over trying many different methods, but every time, it keeps saying "read error" and won't go any further. I am using DVD decrypter to read and write. My disc has virtually no scratches, so I don't think scratches are an issue. In the back of the manual, it mentions "RSA BSAFE SSL-C and Crypto-C software" have been installed. Is there some type of protection on this disc? If so, how do you get around it?
