CD quality scans slow down intermittently on BenQ/Philips
Posted: Sat Dec 02, 2006 8:46 am
I cross-flashed my recently purchased Philips DVDR 1660K with BenQ 1650 firmware to take advantage of the diagnostics available with CD-Speed.
Today I tried a disc quality scan of a couple of CDs and found that the drives slows down to just about 0 at various positions (as shown in the attached graph). This isn't a display artifact- you can har the thing slow down and the first time it happened, I though the program had died.
Also, it plays havoc with the jitter statistics because the jitter value goes up at each dip (it goes to 0 on the advanced quality test).
Is this normal behaviour with BenQ drives?
