hi, ive been trying to back up my copy of red dead revolver using dvd decrypter and alcohol 120% and for some reason, they both run into an error saying that it cant read a certain sector. ive also tried ripping it with my friend's dvd recorder and the same thing happened. ive backed up a few other games just fine, so i dont know what the problem is. im not entirely a noob at dv backups and i have spent hours reading the threads on this great site and i havent found a solution. any help would be greatly appreciated, thanks.
