ok, from what i read, you want to backup a DVD withOUT the "This is a backup of a DVD" screen that you get from using the X Crapy products, I would use DVDShink the new 3.2 delivers good quality and its pretty simple to use. Make sure you do Deep Analysis, as this makes it so Shink uses as much space as possible on the blank DVD but, leaves enough room for error.
Follow the guide here:

If you get a "cycle redudency error" or some error with that has to do with en/decryption, then use DVDDecrypter in File mode and when Decrypter gets done, select the folder you put the files in (i.e. C:\My DVD Title) using the "Open Files" button in Shrink, then remove the audio/subtitles (if you wish) from the DVD to free up room so Shink does not have to compress the files as much to fit them on the blank DVD.
If you don't have Nero, then have Shink make a ISO file (Backup -> target device -> Image recorder) and Burn the ISO file with Decrypter.
P.S. Keep the compression setting on "Automatic"
this will make it so Shink doesn't over/under compress.
