DOOM 3 (CDx3) Transfer to 1 DVD Disc? HELP?

I have the full retail version of DOOM 3 with the CD key and everything, but it is on 3 CD roms discs and I just recently got a DVD burner. Anyways I wanted to take all three discs and put onto 1 DVD. How do I do this, what software will I need to rip and burn and also will I have any problems getting my CD KEY to work on the new DVD version I will be making????Im new when it comes to ripping and burning games, but not a total noob cause I do backup DVDs.

 

I followed all the instructions on that thread and no luck and then I even downloaded the MSI file that was already modified so I wouldnt need to use Orca and I still get the same problem when I go to boot Doom 3. I also noticed that someone else on that thread had this problem but no one ever responded to it??
Anyways when I launch Doom 3 it gets to the loading screen and then OPENGL gives me this error log:

glprogs/nv20_diffuseColor.vp
