Unfortunately,nothing about reading capability-error correction changed
It still can't read cds which were written with my notebook's dvd-cd burner at 24x(it's max speed).But if i burn cds wihy my notebook's dvd burner at 8x,then Lg H62n is able to read it without problem,but then seems likes this mean H62N's burn error correction capability is not good,because my other dvd-drive are able to read the same cds.
I am using this dvd burner as the only optical drive-writer,maybe i should add another one.
