I have a mid-2010 Mini I recently decided to setup in my bed room as a DVD player/Netflix streamer. So today I put in the new movie from Netflix (DVD rental) and it wouldn't work. I tried it in my DVD player downstairs and it worked just fine. So I grabbed some old movies I own: one released in 2011 and one released in 2006. Only the DVD from 2006 will play, or even register that it was placed in the drive. The other (newer) movies just spin and the drive makes some noises and then spits them back out, the Mini doesn't even acknowledge that I put anything in the drive. No, "Disk Unreadable" or other kind of error message. Just spins the disc and spits it back out. Any ideas about what is happening?
