It's simple, in CloneDVD, just access "write existing data" and make the source your drive with the 1st copy.
Drive Let's start at the beginning. Put a commercial DVD in the drive and post the results AnyDVD gives you. Then do the same for the back-up. Need to make sure your drive works.
Thanks for the response. I know my drive works, because I am backing up a dvd right now. it just doesn't detect my copies. I used to use DVD Shrink, and those had no problem detecting.
