if you are using dvdfab platinum, NO. you only need dvdfab and imgburn.

in settings uncheck 'Delete temporary files when done' and 'Create Files in subfolders of Output Directory'. then do a main movie backup of Batman, burning to dvd. your Batman is still saved on hard drive. (although is in video_ts folder and not ISO file). i do this to save steps. this way you can make a backup and still save the files in one process.
