Very off color in videos

[screwtheworld95]

Here's my problem, a little bit ago the video on my computer started to look very poor. The colors were all correct but off shades in different parts of something that should be the same color. Some videos were just very faint with a white like haze over the video. This apply's to avi, mpeg4, mpeg2, mov and other's that I can't currently think of. I have sent the video to my iriver, another computer and on my dvd player and in all cases the files were fine. Any video displayed in a game works fine. I have a geforce 6800 gt graphics card that as far as I can tell is working fine since it is only this one problem. I have 2 viruscanners, a trojan scanner and 2 spyware apps that have found nothing. Does any one know what has happened? Is there a way to uninstall all my codecs and reinstall them? Any help would be appreciated. Thanks.

edit: Ok I feel like an idiot now, I went to look how to capture a screenshot from the video to show what exactly I was talking about. The post said to turn off overlays in wmp. Well I did that and the video is now perfect. So thanks to Alan69 from the topic "How to capture a photo off a dvd or mpeg file?"[/url]

It's good of you to let us know that you solved it yourself. You never know, somebody else may have the same problem.

But you still have an unexplained problem with overlay. It should work OK

Overlay adjustments are in display properties, settings, advanced.

Thanks for the help edDV. By changing the gamma correction and brightness the video now looks great even when in overlay.
