I had some strange problem using my 1653S to build an image of a DVD-movie from a DVD+R disc. It was not copy protected or anything and I used the most current firmware (both omnipatched and stock).
Although the DVD was read and everything seemed to finish without errors the final image-file was “invalid” when trying to read it into Alcohols virtual-drive.
The same DVD was read into a perfect working image-file with Alcohol when using my old Pioneer DVD-Rom.
Also I had no problem reading the same DVD into an image-file when using the 1653S with Nero. The Nero image could then be read without problems using Alcohol’s virtual drive.
At last I got no problem when reading a pressed DVD using the 1653S with Alcohol.
So how can it be that the DVD+R didn’t work and didn’t even report any errors during the copying process (2,2gb of the DVD were used)?
