If i set the write speed on 2x and go to burn, it will burn it with 8.8x I have one on my laptop..same One with a Samsung DVD burner..same One with a LG Blu-Ray..same All write the discs with 8.8x. I have change the settings on aut. write settings..where you can see the disc ID, have add 2x speed for that disc, but still it does it with 8.8x Whats wrong ? The disc does not support 2x ? But it says 1x-48x ? Please Help.
