White captured frames

[yakichan]

Problem: When I capture a frame, the jpg is only a white image.

Well, I have looked for a solution all over in the forum.
I have changed the preferences of bsplayer .499 version (and .493): the overlays, the old rendering, the rgb mode... and nothing
I have uninstall the codecs, and use regsrv32 to unistall filters but I have not solved the problem. I have tried fresh intalling... and nothing.
I know the problem is a filter because I have tried to capture with another computer (with few fresh installed codecs) and It works!

Any idea?
