[Questions] - ISM DVD

Hello

I have a question for you.

I have both -ISM DVD & VHS. And also videos in my computer that I found on the net.

Question :

My DVD who is about 40 mins is not the same that the video  that I found.

I don't have this part in my DVD


Here the video  and here a part of the DVD version

But for me there is only 3 versions for - ISM (DVD, VCD & VHS ). The VCD seems to bethe same as theDVD.

Does anyone know wherethis capture comes ?

This questions bother me since years  >_<

Thanks in advance.

Ps : By the way, If someone needsI canripand up myDVD.
