I am getting Power Calibration Error while burning DVD. I searched through the net and found some suggestions like, 1. Disabling IMAPI CD BURNING COM SERVICE 2. Write at slow speed 3. Change the power connector to the DVD 4. Use high quality DVD disc (media) 5. Update DVDs firmware I tried all the above suggestions except updating firmware. My DVD model is Sony AW-G170A. When I install this firmware I get the error Target SONY AW-G170A is not found correctly. Why I am getting this error message. What can I do to fix this. Thanks for any help!!
