I have been using DVDIdle Pro(22.214.171.124) and DVDFab Platinum(126.96.36.199) to back up DVDs before letting the kids get at them. Most have worked fine, but a few have resulted with menus that do not point to the correct place on the disc, and the title/chapter times don’t display correctly. For example, “War of the Worlds” plays just fine if I start at the beginning and let it run to the end, but if I try to go directly to any chapter beyond chapter 12 using the menu, the movie locks up. Going to a chapter before that gets me to a point on the disc that does not correspond to the actual chapter. I had the same problem with the DVD “Big Fish”. I am using several different burners (Sony, LaCie, Lite-On) to make the backups, and two different stand alone players plus Win-DVD on the computer, with no change in the results. I would appreciate any feedback, because I am out of ideas.
