I have a NEC DVD/RW 3550A that has been working fine for about three months now. However, the other day when trying to copy files from a burnt DVD I got an error message (that I donâ€™t remember, unfortunately) and the copy process stopped. Since then the DVD unit doesnâ€™t recognize commercial DVD records any more, and all â€œhomeâ€ burnt DVDâ€™s are blank according to the computer (wxp). Only CDs are identified correctly.
When I try to burn a DVD I get a â€œPower calibration errorâ€
I have tried to uninstall/reinstall the DVD, but that did not fix it.
