After a took a look on some DL-scans I saw a few DL-media have the layerbreak on half the capacity of the DL-media, most have the layerbreak on the half of the burned data.
All these DLs contains data, not DVD-Video
I used different burning software, mostly Nero 12 Essentials and Imgburn 22.214.171.124.
On which component does the layerbreak depend? Software, DVD-writer, … ?
