Video Playback Problem - flashing vertical stripe and shadow

[[S]oft]

Hi,
Please help me figure out what's wrong:

I have winxp with winamp, wmp, and vlc. I also installed ffdshow, which I later uninstalled but the problem remained.
I think this started as soon as I got my computer, but when I play video on any of the players I get a wide vertical stripe towards the left of the screen that sometimes flashes pixels or sometimes just distorts color over that part of the video. This is coupled with a shadow effect of the entire frame in the background.

I uninstalled ffdshow but the problem remains. Any suggestions?

I had a problem with this in VLC and had to mess with the deinterlace settings

that didnt work, but i started messing with the settings, and what fixed the problem was running the video using directx instead of default. thanks either way!
