Problem with video playback (software)?

[GetInMyFatBelly]

Anyone know why a few days ago, all of a sudden, almost all of my video files on my computer are suddenly playing back in what looks like zoomed in on the upper portion of the video frame (can't see the bottom 1/3 of the screen. This is happening with WMP, RealPlayer, ATI File Player... I think it's something to do with the codecs?
Thanks for any input

What program are you using. If you really think it is codec problem. Just reinstall them. That might work. And update your drivers.
