Franck, I noticed the burn was in trouble when it reached the layer change. The beginning of layer 1 was written at normal speed, then suddenly dropped off sharply and speed didn’t pick up again until quite a bit later. The writer clearly didn’t like what I’d fed it
So the scan wasn’t a surprise really, but there’s no damage on the disc visible, so it is a manufacturing issue. Maybe a dud, I’ll try more discs.
I will have smaller discs to burn anyway, but since this one was not even a full disc, only 7.6GB, leaving almost a GB unused, I’d be very disappointed if what you say is the norm with these discs.
Albert, speed was 8x, I’ll try 6x next.
Edit: Franck, the disc was a copy from an original DVD Video disc, no changes were made and the burn was made with the latest IMGBurn software. Should I try using the Litey for burning these discs? I only have that one, a Pioneer 111 and an older Plextor 716 available, the latter two I think are not familiar with MKM003.
