Using DVD Decryptor or DVD Shrink, I get the error message "Cyclical Redundancy". I am now unable to make any copies of my copies. The error message show up before copying begins. Even Nero Recode will not copy the copies. I even tried to just copy the files from a DVD copy into a directory on the hard drive -- I still get the "Cyclical Redundancy" error. It always fails to copy one of the files. I now can't make copy movies of my copies that I copied a week ago. The disks I'm copying are clean. The disks I'm copying to are clean too. I am able to copy original movies. This problem began after I reloaded Windows, DVD Shrink, DVD Decryptor, and Nero. I bought a new copy of Nero. I've installed and uninstalled DVD Decryptor, DVD Shrink, and Nero -- didn't help. Anyone else had a similar experience? Anyone fixed it?
