Hi I've tried burning a data DVD using Nero 188.8.131.52, however everytime it gets to the copying phase the progress bar freezes at random (once at 10%, once at 33%, once at 74% etc.) The timer continues (I've let it run to over 45 mins with no activity) and I can click to cancel, but the DVD will not complete or be read. I have an NEC 3500AG Firmware 2.18 Official. Any advice is most appreciated. Thanks!
