Desperado/El Mariachi

My copy of this movie has one movie on one side and the other movie on the other side. If the file is not to big or needs a lot of compression I would like to put both on one disc. I have DVD Fab 5.0.9.5. Any help on how would be great!:confused:

OOOOOPs! What I should have said is there a way to do this with just one drive?:doh:
