I upgraded my 2008 MacBook Pro from Snow Leopard to Mountain Lion. I had wiped my drive clean before the upgrade (ya, I now know that was unnecessary Now, when I try to use the Application Install DVD that came with my MBP it won't mount. The drive takes the DVD, spins it up and down a few times, then shows 'Untitled DVD' on the desktop that when opened is blank. Other CD's and DVD's work fine. I've tried using an Optical Drive Cleaning Disc, confirmed that the “CDs, DVDs and iPods” option is enabled in Preferences, re-setting the SMC and even setting the date back to 2009 for Disc Permissions (or something like that Is there a solution? Thanks
