dvd +&- R burning error with nero, alcohol, and . Should i buy a new dvd rom drive?

Ok here's the problem, I was trying to burn a backup Playstation 2 dvd
using nero 7 premium and during the process it came up with an error message,or actually the log window said it.
it said: Caching of files started
Caching of files complete
Burn Process started at 12x(16,620 KB/s)
Power calibration error D: OPTORITE DVD RW DD1205
Generating DVD high compatibility Borders
Power calibration error D: OPTORITE DVD RW DD1205
Could not perform end of Disc-at-Once
Burn process failed at 12x(16,620 KB/s) and thats all
Also can someone tell me what it means by power calibration error.

Sorry if this is a stupid question but im not a newb with computers its just i have not taken the time to learn much more than the basics on dvd rom drives

I did save the log file so if anyone would like to see it plz post a reply and ill paste it on the next message because i tend to put only enough info in my messages to give people a good enough idea of my problem.

I tried burning other iso's with nero and the same thing happened then i tried other programs like alcohol 120 and ultra iso and same results so a reply would be very much appreciated so thnx in advance.
