NED DVD Burner can't see blank DVD

Hi everyone,
I just bought a brand new PC with a NEC DVD burner. I can copy DVD’d by using CloneDVD, but when I put a blank DVD in to copy some other files, it recognises it as a CD. I tried different DVD’s, all DVD+R, and it still won’t work. Did anyone else have this problem? Any help is greatly appreciated.
THanks,
Claire

I doubt it recognizes a DVD as CD. Maybe the explorer shows that, but it’s just the explorer bug we know.

Just use a good burning app and it should recognize a dvd as dvd media.
