I put a DVD in my DVD-ROM and tried to copy the VIDEO_TS dir to my HDD (in preparation for backing it up) but when I hit CTRL-V (after hitting CTRL-C) DOpus just terminated.
Doing the same thing in Explorer showed the error "Cannot replace or create VIDEO_TS: File system error (-2147351799)"
Now obviously it means that the DVD is encrypted however DOpus should not terminate. I would have expected it to show the same FS error.
P.S. I have got round the issue so this was purely a heads up for u guys.
