Newbequestion about color controls

At first,i have already read the FAQ.
Color controls works fine with DivX5;3.11 and ffdshow.
With BSPlayer Build 498;499;500 they don't work.(overlay checked)
I made also a test with Crystal Player and color controls are working both with AVI and MPEG files.
I'm a little confused because I don't know if the problem lies on my video card :?
However BSPlayer is my favorite and will still be anyway 8)

best regards
