[QUOTE=DrageMester;2781361]Dubbing speed will not affect picture or sound quality.
It [I]may[/I] affect readability of the disc, but slower is not necessarily better.
HDD-DVD recorders typically have the capability of re-encoding when dubbing from HDD to DVD in real-time (1x); this will reduce picture quality, but might be necessary in some cases such as e.g. fitting the content onto a DVD. I don’t know if your specific recorder has this capability.[/QUOTE]
