I have burned several TDK 8x -r by my 1633s@sony710a.
if i select 4x testing speed, the result is very good, PI < 5, PI < 1but when I use 8x , the result is bad. I dont know why.
because the disc is being read faster and this usually means it will show various anomilies like spikes etc, this is why at cdfreaks we use 4x to get a nice clean scan :iagree:
thank you :iagree:
