Search the forum on DVD copies, and you will find many with difficulties. It is possible to get a burned copy to work, and some folks have no problems what so ever. However, it is also likely that copies will cause the MKIV to crash frequently. So, stick with original disks. They are faster and much more reliable in the MKIV computers.
