What I said is that I just bought a new video card. I used to have an X850 but I needed to upgrade. This even happened with Quicktime as well.
Also, I did fix this issue by reinstalling Divx and that helped, now its happening again and I reinstalled Divx again, only this time it didn't work.
And yes, I went to upgrade both Winamp and WMP and that did not work at all.
