Ext Memory in EXT jack on rear of unit not recognised. Check ext memory, turn power off, then on again - done that , it does not read any DVDs or CDs - I can hear the lasers tracking back and forth but not the disc spinning and I know that cause was quite a anoying sound, could hear it from the couch.

Did the Live Chat with Sony, and they said if you reset the unit (unplug it for a minute and plug it back in) that should fix the issue. If it does not (in my case, it did nothing) the unit needs to be sent in for service. I'm taking mine back to the store in hopes for a refund. Good luck!

I had the same issue. it is not recognizing the disc. I called in and I am having to send it in for servicing. The message you are getting is because the only option you are getting is the BD data one and not the one to play the disc.
