This is from a Nero site:

Power Calibration is controlled by the recorder.

Before any write operation, all recorders must do a 15 step power test to determine the optimum power for writing to the CD; this is called "Optimum Power Calibration"(OPC). During the write, it continues to do this test to get the best write throughout the whole CD; this is called "Running Optimum Power Calibration" (ROPC).
This whole process is controlled by the recorder, though initiated by programs such as Nero. There is an area on the inner part of the CD for the test and test data info to be stored. You can use this area up to 999 times.

If you receive the "Power calibration error" or "Power calibration area is (almost) full" error message, the cause will be either poor media, poor power, or a defective recorder.

It's discussing CDs, but DVDs use the same method. First I would try different media, then it could be a power supply problem, especially if it's an external drive, or it could be your burner is failing.
