I really need a little more info, but here are somethings to look at. 1. Are the images and files there on the disk, you can see individual items? 2. Did you use Adaptec software to burn?? Adaptec loves to make images out of everything. 3. If you can see the items, did you copy them to you harddrive first before you tried to use them? If you did make sure the archive, and read only is not checked. That is about all I can think of right now, hope that helps you.
