I have had the same problem with three different versions of the DVD for The English Patient Disc 2 (Special Features). When copying gets to 99% the following message appears: "Creation of you DVD was not successful: Invalid block code" "one or more blocks might be corrupted by a prior copying process or by the source device covering critical read errors. Try copying the video files to your hard drive (again) and retry." Several retries bring the same result. Have not had the same problem with any other dvd, nor even with The English Patient disc one, which copied and cloned fine. I am a new member and recently downloaded the new version of Any DVD and think I have the newest version of CloneDVD. Any help would be appreciated.
