I have a Dell PC with Windows XP Home Edition SP2 and a NEC 1100A burner. I was able to successfully burn 3 DVDs with no problem using DVD Shrink and Nero. The media is Maxell +R from BestBuy. After burning three successfully, I have not been able to burn any addition DVDs. I either get burn process error message or it tells me that the media is not empty. Not sure what the heck happened here. Several topics in these forums seem to suggest that the media is the problem. I've already went through about 10 so far with no luck. Any ideas?
