Cant burn memorex disc



I have a nec-3100ad and i cant burn anything with my memorex disc. I’ve checked for a firmware upgrade and nothing. everytime i try to burn something a dvd or a data dvd i get illegal disc and basicly error. Do i just have bad disc or need something? Im using dvd+r disc


Try another media. Best Buy has a sale on 8X DVD+R media from Fuji. Look for made in Japan on the box. $20 for 50 pack.
