After variety of different tests and findings I have resolved this issue. It appears that the DVD burner was not in good working order and the DVD player was not at fault. Thanks you to all who answered and responded to my problem. Many thanks.

Hi mgarragh1,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Replace the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.

Ifyou already cleaned the lens, and confirmed that the ribbon is good as well as the motor then I would advice you to send it to repair shop because the next step should be done with an expert because it is quite technical diagnosing the fault between the pick-up lens and the main board.
Hope I helped you.
Have a nice day!
