2 or more DVD writes to one disk?

I have two avis. One is called CD1 and the other is called CD2. I am pretty sure they will both fit on a DVD. I am using VSO DivxToDVD to make the vobs and info files and then write them to DVD. I can do this easily with CD1 just one. But I’d like to write both to a DVD in order CD1 first CD2 second and have CD2 pick up when CD1 finsihes. Can I do that with VSO software? Thanks.

Best solution would be to join the avi files before using divxtoDVD to convert to dvd compliant files. Use a free program like Virtualdubmod to join the avi files into one big Avi file.
