You can merge multiple DMG files using your Mac's Disk Utility. A DMG file contains a compressed package that usually includes a program, backup or a compilation of files. Before you can view the individual files in a DMG package, you must first mount the disk image to your Desktop. After mounting the image, you can select all of the files contained within the DMG package and combine them into a single DMG file. Using Disk Utility, you can then burn your combined DMG package to a DVD for storage.
