Hi there and welcome
What exactly happens when you try to play a DVD? What does it do?
Can you please remove the power to the recorder (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the unit, turn it on and tell me please if it is now operating correctly.
Let me know the results please
I want you to reset the device please
Can you go to Settings, Initialize, then choose Shipping conditions
Complete this, do the setup and when done tell me if it now reads DVD's please
its under Basic Settings, page 88 of the manual here will show you
It is the internal mainboard or laser for the DVD that has faulted.
I am really sorry about this and you are going to have to return the unit to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
