My new LDW851S will only allow me to burn regular CDRs or CDRWs, not DVDs. When I try to burn a DVD under Windows XP (which is up to date) it won't allow me to. This is consistent even when I use different software packages. I was able to image my harddrive using Norton Ghost however that appeared to work at a DOS level. I can watch DVD's fine, when I use DVDXCopy Xpress for example, it rips the DVD fine but I won't get the green start button to light up when I go to burn the DVD. I have used different media and still have the same problem. Any suggestions?
