I know I must be missing something but I can't get dvds to play either on my mac mini with Snow Leopard or with my Macbook Pro running Mountain Lion. Dvd Player opens but that's it. I checked Preferences and they are set to start playing the dvd; I know this used to work but it's been so long since I did a dvd that I don't know what happened. is there something I have to do to get this player to work or is there an accessibility issue? -- Cheryl May the words of my mouth and the meditation of my heart be acceptable to You, Lord, my rock and my Redeemer. (Psalm 19:14 HCSB)
