I am having trouble with Nero. Each time I try and copy a dvd weather it be avi files or application files, the process fails every time. I am using nero 7 and vista home premium. Can anyone help me on this?? I have a Lite-on LH20A1S and a Pioneer DVR 215D. Both drives worked fine until a week or so ago. My machine is more or less brand new. I have tried Ritek dvd-r, Maxell dvd+r and a supermarket own brand. Each time the process failed. I have tried copying from disc to disc aswell as using the one drive as a source and destination. I have tried this with both drives aswell as when I tried to copy from disc to disc swapping them over as source and destinations drives. I can only assume it must be a software problem. Thanks in advance guys.
