Hi, I've tried all manner of searches on the CD-Freaks forums without any luck solving this - I THINK it's probably something arcane in Vista, but possibly a hardware issue...
I'm trying to run DiscSpeed 126.96.36.199 or CDSpeed 188.8.131.52 under Vista Home Premium on an Acer Aspire AM1641 media machine with a SATA HL-DT-ST DVDRAM GH15F which does just about anything (see graphic). All Vista updates installed.
Under Disc Quality, when I select Quick scan then click on Advanced to get to the Speed/Accuracy slider, the 6 'Enable' boxes are unchecked, the slider is greyed out, and there is no content in the 'Scanning interval' drop-down. In other words, it looks just like that Advanced box looks on my main PC under XP Pro when there is no disc in the drive (a Sony DRU810A). Yes there is a recognized DVD-R disc in the Acer drive (burned with the latest DVDFab).
I've tried all posssible settings under 'Compatibility', including switching off Aero etc. for the software executable, with no change. And I've gone into Security and taken ownership of the DiscSpeed EXE - still no luck. ANY help or suggestions would be vey much appreciated and acknowledged, with heartfelt blessings upon your head!
