automation of Master DVD image

Hello! I am just starting to learn about applescript and the automater with MAC OSX. I want to be able to create a DVD template (manually) with DVD Studio pro and then be able to automate the workflow in creating different DVDs when I provide different mpeg files. For example if several people in our office want to create an 5 minute video “blog” and then put it on DVD we would like to be able to just put the mpeg file into a directory and have DVD studio output the master DVD file. We do a lot of individual mpeg, but want the exact same DVD template. I am not sure if that makes sense, but I don’t know where to start. any suggested reading or starting points for an amatuer?
