Just as a test, decrypt the dvd to the harddrive first with dvd decrypter. Then try to run DVD95Copy on that location.
I've had that software since its first versions. I've reported to the author a number of times about it not decrypting properly. See if thats what the problem is.
Actually you would probably come out better using DVD Shrink. It gives getter results from what I've seen and its free. It also has a lot more features.
