I have a samsung TS-H552B burner. At one point of time it used to burn only moser baer dvds and would never ever churne out a good sony dvd. Now the burner just refuses to burn a moser baer dvd. The errors i get are either 'Power Calibration Error' or 'Session Fixation Error'. What does this mean. I read in a few other threads that the power calibration error is due to low quality media, so i tried burning with different media but i still get the same error. Could there be a problem with the burner or is it just limited to the media. Any help will be appreciated. Thanks.
