I'm running OSX 10.6.8 and am try to burn some jpegs to a DVD. I select the files I want in FINDER and right click. I select "Burn 62 items to disc" and follow the prompt to insert a blank disk. I put in DVD+R and nothing happens. After waiting 5 minutes, I click CANCEL and get the message "This disc can’t be used because it’s not recognized." The files require 252 MB and the disk hold 4.6GB. It is a Memorex DVD+R Any help would be much appreciated.
