I started this little disagreement, so let me calm it down by saying, that I did not intend to ridicule or abuse you in anyway.
I have been involved in CD/DVD laser technology for more years than I care to mention. I was trying to assist by pointing you how these products work. I have many more links and recommended readingsif you are interested?.

As someone who understands this technology I cannot help but dismiss these "tweaks" out of hand, just like you would dismiss the idea of putting water in the petrol tank of your car for increased performance ( would be nice though when you see the price of a barrel of oil these days?)

You wouldnt do it because you know how an internal combustion engine works. I wouldnt use these 'tweaks' because I know how a CD player work.
That is all. I hope I didnt offend you as that was not my intention.

I have chosen Meridian because they also know how a CD player works and produce state of the art players. Still over priced by hey! they are allowed to make money after all.
