I followed the tutorial on this site to backup a DVD-9 onto one disk. I used Decrypter, Shrink, and then Burnatonce. Everything seemed to go fine ( I followed the tutorial to the letter), but when I burned the DVD using burnatonce, it only burned half the movie onto half the DVD-R. The DVD-R popped out of the burner within 16 minutes and said complete ( even though the progress bar was at only 50%). The DVD-R even plays on my home DVD player, but only goes up to 16 chapters ( the movie had 32 chapters). Any help would be appreciated. Thanks.
