Wrong ratio
 

I have some movies (BS-player says, they are 1440x1080, the ventor 1920x1080), when I'm click on them (or they start from the playlist) they appear first in ~4:3 (BSPLayer opens the movies on my secondary 16:9 monitor in full screen, I see a sqeezed yideo with black bars to the left and right), as soon as I click in the control window (on my mainscreen) on 'Video' (right side bar) the ratio changes and fit. I do not have to click the sub menu 'aspect ratio'!
Any idea how to get the vids automatically in the right scale?
