I'm afraid only the latest DVD players in the B&O range (that is, as from BV7-40) are making it possible to step through DVD chapters by a simple pressure on the arrows. Before that, you needed to press GO, then the arrow (BeoCenter 1, DVD1, BV7-32 etc). On the contrary, when playing a CD audio, only one direct pressure on the up or down arrows skips through tracks!
It would be so great if all B&O DVD players spoke the same language, hopefully the forthcoming products are more logical & user-friendly than the first ones..
Reunion Island is greeting you!
