Sometimes, there are "Special Features" of a movie on a second disc, which makes the DVD a 2-disc Special Edition or something like that. Recently, I have rented the 2-disc Special "Artificial Intelligence" DVD, region 1 of course, and it has all the special features stored in Disc 2. As you might know about these "goodies", there are seperate individual clips which users can see and choose one by one via the DVD menu, and I actually need to extract a specific scene. As I was told previously, I played every single clip I can find in the DVD from start till end, by none could be extracted by SmartRipper 2.39. All the .VOB files were locked again. However, using another stand-alone software called Dup-DVD, I was only able to rip clip "Alpha". No matter how many clips I play, how many times I do it, Dup-DVD can only read clip "Alpha". Mysteriously as it sounds, only this "Alpha" clip can be read. The rest were locked. So, is there any software that can bypass these "locks" and restrictions because I find playing it with a media player just doesn't work... (BTW, I use InterVideo WinDVD v3.10 to play DVDs) Is my DVD drive causing this problem? Or is it the DVD? Thanks in advance for swift response and reply to this question!
