Hi all On my Windows XP Home pc, I have recently installed a NEC DVDRW ND-4570A but, when I try to access it to burn a DVD, I get an 'incorrect function' error. The drive didn't come with any drivers so I used Windows drivers when installing. The drive works fine with CDrW's. Could it be that Windows just doesn't burn DVD's and I should be using a programme such as Nero? Thanks Barry
