Nice info. But their is another point except for errors why Yamaha
might be right to claime to have the better system.

Anyone knows that p-cav will make gaps.
And here is where it might go wrong. When useing a CD-R to make a glass master no gaps must be on it else you can't make a glass master.
That's why you can`t backup laserlock cd's with makeing glass masters of them.

However if Acer's info is true and i doubt it seamless link might actually work. (The claim is no gaps. But I doubt it.)
Or if the gaps are really that small it might work, but I don`t think
burnproof or justlink can do it.

Will Anyone ever check this ?
Well I don`t think so, because each glass master you make will cost you arround $330. So it will be way to expensive.

So if you want your music released on a normal cd then you will have to record it without useing z-clv, because else you can't master it.
