@elupus : I have posted a forum thread here (http://forum.xbmc.org/showthread.php?tid=187379) to ask devs their opinion, and this was the preference (till now). The underlying reason being that more DVDs play well with it turned on than with it turned off (see the two trac tickets that led to this choice). Even more so, VLC has this on "by default" (also see forum post).
