I think my 1213S is defective, I suspect a laser problem. I’ve tried the 1213S -> 1633S firmware from codeguys. That firmware seemed to work, but not completely. So I switched back to the original firmware for the 1213S.
Unfortunately, I can’t burn ANY dvd’s any more (Nero and DVD decrypter), they fail with Power Calibration Errors. I’ve tried several new DVD’s (different brands).
The ONLY dvd I can manage to write a DVD+RW.
Is there something I can do to solve this?!
