"File 1 E:/VIDEO_TS/VTS_04_4.VOB 23 TCSectorReader" This is the error I receive when trying to use clonedvd2 to process a backup I made of the movie. The reason I did this was because "PowerDVD" would give me a "cycle redundancy error" when 2/3 through the movie backup I made. I wanted to know what clonedvd2 would find. It found the same .vob that "PowerDVD" said was the problem. I used anydvd with clonedvd2. First making files of the movie in a folder. And then creating a backup with the "Write existing data" choice in clonedvd2. p.s. This same error was found on the 2 backups I made. Used TY dvd-r premium.
