Yesterday I burned one Philips DVD+R (certified at 8x) at 6x, with my 451S@832S and the Codeguys firmware CG3B.
The strange thing with this dvd is that its error scan looks very good if we ignore the very last part of the disc, but a reading error occurs approximately at the middle of the disc.
Notice also those PIF spikes and their pattern…yes, it seems that they occur when the CG3B recalibration “feature” kicks in…so I think that the error is caused by one of those recalibrations. I’m not saying it is a CG3B fault, I’m saying it’s probably an overclock limit of my 451S.
My hypotesis is that my 451S@832S doesn’t like recalibrations at speeds > 4x in certain points (in fact at 4x I had PERFECT results with CG3B and dvd+rs) and one thing that strenghten my hypotesis is that when I tried to burn at 8x in the past with VS0B firmware a similar error occured in the zone where the speed increases from 6x to 8x. I have to say also that at 6x, with VS0B, I didn’t have any problem…maybe because the recalibration zone in which the speed goes from 4x to 6x, doesn’t give problems.
There’s anything I can do about this? Should I stick with speeds < 6x with CG3B?
Any help will be appreciated.
