yes, you CAN do this without any trouble. as long as you are just using the discs to transfer media to the other machines - i wouldnt work from the dvd's
its just a matter of the time it will take and the space needed. copying to and burning a full dvd takes around 20 minutes... and then transfer time again at each machine...
i would suggest just getting a cheap external firewire drive and just move that from machine to machine. time IS MONEY
