Multi cd`s to dvd

This is probably already somewhere in here but i cant find it. Anyway I have a four cd game and would like to convert it to 1 dvd. All four disks are in image form now (.bin-.cue) with one disk (.mdf). I would also like to add a folder to one of the disks before its all finished. I remember reading somewhere that you copy the disks over each other. But theres lots of other crap you have to do also. :confused:

Post a link for me to save time if you know of a place where there are directions for this.

         Thanks in advance.

You could extract all binary files (the four .bin files) into one directory on your system, then write it to dvd. But i doubt if the software would ever work.
