With my LG DVD combo drive, HL-DT-ST RW/DVD GCC-4320B, I get a CSS error when trying to read from
CloneDVD even though the
AnyDVD icon greys-out for a moment when inserting the DVD. I found to make it work, I have to right-click on the AnyDVD tray icon, select settings and press OK, then the icon greys-out again for a moment and the DVD is accessed, then the drive is unlocked and CloneDVD reads. Weird!
With my HP dvd200i it works automatically from the tray just inserting the DVD.
