So, do you want it to show up as 2 different cd-rom drives like when you partition a hard drive? I doubt this is possable, and if you could somehow partiton a dvd, it wouldn't show up as 2 cd rom drives. If you wanted to have more than one cd on the computer at one time I would recommend Alcohol 120% to build virtual cd-rom drives. It would really help if you would explain what and why you are trying to accomplish here.
