Ok...I'm on an IMac (2007 White, 24"). Since SL was installed (unsure if that when it started) I cannot burn cd or dvd. Gives me errors, saying the media is unreadable. Ok, I says to myself, drive is toast. Tonight I boot into Windoze and decide to give it a shot. Works flawlessly!! Went back to OSX and still doesn't work. In summary: burns under XP, not OSX. Can anyone "enlighten" me, what this is all about ?
