Okay, so I got a friend who is burning a CD in iTunes 7.5 on her MacBook she bought a few weeks ago and it's taking 20 minutes to burn a CD with 21 songs with the write speed set to "Maximum Possible."
So after she took 20 minutes to burn the CD it wouldn't play. She tried again tonight and I changed the maximum write speed to 12x and it only took about 7 minutes to burn and it plays.
