I have a DVD which is about 6GB in size and has 2 movies on it with a great menu, the menu works like this:

1 Main Menu with 2 links each navigating to another menu associated with the specific movie you choose.

Now I want to split this DVD because i want one movie with its menu on a DVDR if i can split it then i can fit it onto a DVDR without reencoding it.

Is there a guide to do this?
