I have made an ISO file of this DVD, but when i compared it with the original, there were numerous differences. There were no differences or read error when the ISO was being made. Here are a sample of the differences found: LBA=113h Byte=0 ISO=0h Disc=44h LBA=113h Byte=1 ISO=0h Disc=56h LBA=113h Byte=2 ISO=0h Disc=44h LBA=113h Byte=3 ISO=0h Disc=56h LBA=113h Byte=4 ISO=0h Disc=49h LBA=113h Byte=5 ISO=0h Disc=44h LBA=113h Byte=6 ISO=0h Disc=45h and so on.... By the way, I have used other programs to make a copy of this disc and none seemed to work. The file on the disc is not corrupted because it plays fine on my PC. The only problem is that i cant copy 2 .VOB file from it to my HD. A read error saying that the disc is dirty or scratched always appear. All of the program i used say the same thing, although the movie plays just fine. DVDInofPro was the closes thing there is that made a complete copy of it. The only problem is that the copy is different from the orginal. Please help if u can.
