Why are My Videos All Pink?

What happened to me was that after running a Windows Update, suddenly all of the videos that I played in Windows Media Player played with a pinkish/purple tint. I couldn't figure out what happened. Videos that played in other players weren't pink tinted at all. VLC Media Player was fine as was Apple Quicktime.

What it ended up boiling down to was that an update for Windows Media Player broke my video card drivers. So I reinstalled the video card drivers for my NVidia GForce 7900GT and rebooted my computer. After the reboot, all of my videos were back to normal.
