Add files to an existing image (DAO)

Ive gota vista dvd (GENUINE).,Bootable. I would like to make a copy and put all the other progs that I need for my notebook (like TC,WinRar, Kapersky etc.) on the same DVD.
In short,can I convert a bootable single session image into a multisession, that is still bootable.

Perhaps Vlite can help.
