I have very large image files, about 75MB each. In the process of getting these images to a client, I began burning them onto DVDs. I burned 2 (DVD-R) DVDs of some of these images but after burning the DVDs, removing, then reinserting them into my (Mac Power G5) computer, the icons don't appear on the desktop. I recently had another HD installed, so plenty of room. I've never burned DVDs before, only CDs. A friend did help me to find out that my Mac reads any kind of DVDs.
