Why is there not a setting option that will place the layer break at the same point that is on the original DVD? That would make it much simpler.[/QUOTE]
The disc is altered as part of the copy process (even if it’s only the removal of dummy sectors and other copy protection techniques, or as a result of the deliberate removal of audio streams or other unwanted content) and the original layer break position isn’t necessarily optimal anymore.
Most users therefore want the option to check this (as described in the guide) rather than finding out after they’ve burnt the disc.
DVDFab removes the layer break by default but you can override this if you wish by going to Settings>DVD/Blu-ray>Protection>DVD and changing it there. Read on though before you make a decision on this.
ImgBurn does already check for an existing layer break position and if there isn’t one present it will make its recommendation on the basis of the file system/IFOs.
Even if you select a position that ImgBurn has marked as ‘excellent’ though there’s no guarantee that it will in reality produce an acceptable transition. The odds are more in your favour that way, but there’s no guarantee that it’s the best one.
This is because ImgBurn doesn’t analyse the actual video content in any way and it therefore requires human intervention to determine if the transition will actually work satisfactorily in practice.
So in my opinion you’re therefore better removing the layer break and choosing the best one yourself.
