weird looking colors on wmv playback

[gordon_fan_24]

Problem is exactly what the subject describes, This problem occurs when I try to play anything with the .wmv extension on my computer, including anything I've converted to wmv from VS9, or just a video downloaded off the internet, or from emails. I've attached links to 2 pictures, one is what it should look like from a screenshot taken on another computer, the other is what I get on my editing computer. The screenshots were taken as the video played, so aren't exact duplicates, but are taken within a second of each other. Can anyone look at this and tell me what the proble is on my system, and how to fix it. I am thinking it is a codec problem, and if it is, I don't know how to fix it. I believe my system specs are up to date, but if they aren't, I will update them as soon as I get on that computer to check the specs.
