3. Split the DVD
        Load 
          up IFOEdit and hit the "Open" button. The goal here is to 
          pick the set of VOBs that contains the main movie (not the bonus materials/menus). 
          In most cases, these are the ones that take-up the most space. Again, 
          in this case, they are VTS_01_x.xxx. So load up the file called, "VTS_01_0.IFO" 
          into the program. Then go to the "VOB Extra" menu and select 
          "Split to 2 DVD-Rs" as depicted below.
        
        From here you will see a dialog similar to the below figure. 
          There is no need to change any of the options; the defaults will work 
          just fine. We do however need to fill in the two paths we created before 
          into "Destination directory" and "2nd Dest. directory" 
          as I have done below.
        
        When you have done so, hit "OK"
        
        You will then get the Stream List dialog showing all the 
          chapters and cells contained in this title-set. The Cell where the layer-break 
          is located show be preselected by IfoEdit. I would recommend keeping 
          it as your split point. Some prefer to select another point (which is 
          fine) and in some cases you may have to select a different point. When 
          you ask?
        Some times splitting right at the layer-break is a bad 
          idea. More on this later. Hit "Split it" and wait about 10-15 
          minutes while the software splits and reconstructs the files for us.
        When the software finishes, exit it and reload it!
