Power calibration error" might tend to indicate that it's a hardware problem. Maybe. Do you have it set up to simulate before burning? What happens if you flip that switch?
Switch? What switch? I can find nothing in any of the Nero options about that, but I am using the simplified "Nero Express" aspect of Nero 7, rather than the more complex "Nero Burning ROM", as my needs are very simple: I burn Data DVDs and once in a great while a Data CD. I will certainly look into the CDBurnerXP program, it wouldn't hurt my feelings at all to get rid of Nero. What I dislike most about Nero is that when you install or update it, you have to be
very careful to uncheck every option box or else Nero becomes your default
everything, from picture viewer to Office Suite. Well, not quite, but they're probably working on their own spreadsheet program as I write this.

I hadn't realized how inexpensive CD/DVD burners had become. Not too many years ago a friend of mine bought the first CD burner on the market for $800. I think it ran at about 4x speed, maybe even 2x. I just checked NewEgg and I have a choice of dozens of them for less money than I paid for my last box of blank DVD discs!
Does anyone have any recommendation for a replacement drive? It looks like $30 will let me take my choice of just about anything from NewEgg. My requirements are SATA, and must
not be SONY (I won't do business with them because of the rootkit scandal. I'm sure my personal boycott has caused them great financial distress over the past few years...)
Finally, does anyone have a simple explanation of what the DVD-R and DVD+R business is about? My DVD burner is supposed to be compatible with both, but the last time I tried the DVD+R discs I ended up with 40% coasters, whereas the DVD-R discs I just bought have worked 100%.
