I've just made a scan, have used "faster" mode.
Scan quality went from 93% down to zero after the layer break.
I believe the problem is the media itself, it works fine with Verbatims, but all other DL media is Inverted Stack stuff and the Pio has problems with them at the layer break, at least for scanning.........
OK, here is also a quick scan of the disc. Surely not reliable, but better than nothing.
