Hi, I have got a big problem. When I burn any DVDs includoing data, about 1/4 of the time they won't have an error when i use CDCheck to verify them. They have CRC errors. I have tried 4 different kinds of media. I always used to have luck with Memorex, but now thye are iffy. I have a NEC ND-1100A. I've been thinking about buying a new burner. Any help wpuld be appreicated!
