High Sierra- DVD will burn and play but Will NOT play Commercial DVD
Internal Slot Drive on iMac
CDs work, and there is no Region Message. I've done a reset etc. I have the OPTIARC DVD RW AD-5680H and it shows in System info.
As said above- iDVD will burn and play but I have tried multiple other DVDs and it tries to read and then auto ejects. I have also Cleaned with a brush DVD disk.
I seem to have the latest V3 Super Drive update.
Thanks for any ideas!
