superdrive will not play some discs
My superdrive has started to intermittantly reject (spit out) burned CD-RWs and non-factory made DVDs that it previously accepted and mounted on the desktop. And then later or the next day it will accept and mount these discs...and later not accept them again. However, the drive continues to have no problem with factory audio CDs and factory DVDs. What the heck is going on and how do I fix it so that CD-RWs and custom-burned DVDs from various sources always play as they used to play. No change of any kind was made in my computer, no new software installed or anything else. And as I said, the problem is intermittant, it comes and goes.
