It is time to put on your Sherlock Holmes' hat and do some investigating:
It would be helpful to know if the DVDs play on someone else's DVD player, to find out if your player is the problem.
At some point you need to use a different brand of DVD media, to see if that is the problem.
If you are using DVD-R media, then try DVD+R media and see if that is the problem.
You want to make sure that your DVD burner has the latest firmware. Find out the manufacturer of your computer's DVD burner and the model number.
Then check that manufacturers website and see if there have been updates to the firmware for that burner.
