I recently got a new PC that came with a CD/DVD RW all in one recorder (NEC 3100 AD). The problem is, it doesn't recognise blank DVDs in the drive so I cant write to DVD-R/RWs at all. As its an all in one drive the CD/DVD has to be copied to a temp directory before it asks for a blank disc. With CD-Rs it works fine but with DVD-Rs I get no result. If anyone could tell me why this happens and what I should do I would be very grateful.
