No, only one ISO file to a customer. You can combine more than one ISO into a single ISO however. If both ISOs have menus you want to keep then a commercial program like DVD Remake can help. If you don't have menus that need to be retained, then it can be done by using the Reauthor mode of DVD Shrink, or other programs like Nerovision, TMPGEnc Author, etc. http://www.dimadsoft.com/dvdremake/index.php http://www.afterdawn.com/software/video_software/dvd_rippers/dvd_shrink.cfm http://www.nero.com http://tmpgenc.pegasys-inc.com/en/index.html
