Deinterlace preferences isn't modified to video menu (VLC 0.9.2)
As partially pointed out in here: http://forum.videolan.org/viewtopic.php?f=14&t=50323
VLC 0.9.2 has two ways to set used deinterlace mode. During playback from Video -> Deinterlace or from Tools -> Preferences... and Video -> Filters -> Deinterlace
If I select something from Preferences..., it isn't show as default option in Video -> Deinterlace, nor vice versa. So I can have different settings on both and I don't know which one is applied to video.
