every now and then my nec 3540 or 3550 will start taking a little longer
to burn a premium disk with buffer fluctuation, say 15 minutes for an 8X burn instead of 9 minutes. I always scan those when I catch it. Good burns. Really noticed it when I started using mcc004's again after several months(upgraded firmware since using that mid). Whatever nec's are doing, it's working, but I was curious.
Also happened with tyg02's(which I have used as my mainstay for last year).
