Cant read DVD media with NEC 3540A

Hello, i have a problem with my DVD burner.
its a NEC 3540A. now i can burn CD’s and DVD’s. allso read CD’s
but when i try to read burned DVD’s (verbatim media). windows shows as if the media is empty DVD.
i checked it on another LG DVD drive and the media worked on that one
why is that and now can i fix it?
