burn pictures to dvd
Trying to Burn Pictures to a DVD. Exported selected photos from Aperture to my Desktop. Inserted blank DVD-RW into disk drive which prompted me to open Disk Utility which I did. When asked to select images to burn from disk utility, I selected the correct folder from my desktop, but the images are all gray scaled out so I cannot select them.
Any suggestions
MacBook Pro, OS X Mountain Lion (10.8.2)
