how to split Visual Studio 2003 DVD rip into CDs?

[jonwil]

What I have are 2 things (or I will once I finish yanking them from the FTP)
1.the Visual Studio 2003 enterprise architect DVD
and 2,the MSDN library 2004 april

I want to take the Visual Studio DVD and remove the MSDN component.
Then I want to split what remains into the equivelent files for the various CD the CD version comes on.
I know its possible because at least one person made mention on the board before about it.
