You want to make a compilation (I probably mis-spelled that). You need to give a little more detail and be a little more specific. Are you wanting to put several computer games on one disk? What are the games (copy protection varies quite a bit). I’m not farmiliar with copying games a lot but perhaps someone else with more knoledge might help if they knew more.
As far as getting the dvd’s onto your computer, again, what kind of dvd’s, movies, games, other software?
Fyi, here is something that might help (if it is games or software). You can make an image file (if the disk has copy protection then it is dependant on what the particular software is, and therefor what copy protection it has, to know what program to use). If there is no copy protection, you can make an image file (several programs will do that), and use daemon tools. Daemon tools will create a virtual drive for the image, and the software on the image, as well as other programs and the computer will think that the image file on your hard drive is an actual disk in a disk drive.
