You'll need to "rip" that DVD to some .AVI or other files. http://www.clonead.co.uk/ writes "convert a dvd movie to an avi".
Let me be clear I offer ZERO support for this. But can tell you that step works fine.
Next you use your selected AVI editor.
I recently purchased a Panasonic Home DVD Recording unit and have been recording my home VHS tapes to DVD.
I have a PC that is equipped with a DVD burner.
Can I copy these vob files to my hard drive and edit them???
