--- Comment #9 from Jörg Höhle hoehle@users.sourceforge.net 2010-03-10 09:42:48 --- Out of sync is irrelevant to the present issue. I've already encountered this with other videos as well. xine performed better.
Also before the video plays an error box comes up saying MCI ERROR: Unable to set MCI Draw procedure.
You did not mention whether this error only comes up since the regression or whether that has always been the case.
