≤12× reading speed limit, even for CSS-less DVD-Videos?


DVD-R, DVD+R and DVD-ROM can be read at ×16.
Each of them with DVD-Video however is limited at ×12 for the BE14NU40, even without CSS.
TS-H653B however still reaches ×16 on DVD-R-Video and ×12 on DVD-Video-CSS.

Is there a technical explaination?
