Welcome to the Forum.
As Forum Member BeardedKirklander suggests try using known proven quality blank DVD Media such as Verbatim or Taiyo Yuden.
Usually the problem you are describing is related to the use of poor quality blank DVD Media and/or old out of date obsolete DVD Burner Firmware or a combination of both.
