Green screen for videos using AMD Catalyst Legacy 13.1 drivers

I've finally found the root of the problem, it's some compatibility problem with Microsoft's update KB2670838. I initially thought that DirectX was the problem, but the actual culprit was the update. I installed DirectX before doing the update and tested the videos, all was well, so I thought that it's DirectX's fault. Until I did the update, and since the computer restarted after the update, all videos that was encoded in H264 format was showing a green screen. Did some research and found out that KB2670838 installs a Microsoft version of the H264 encoder, which is known to cause problems such as BSOD and stuff. Uninstalled it, and restarted computer again, the problem was gone, but IE10 was gone with the uninstalled update too (yes, the update is a prerequisite for IE10). So if anyone else is having this problem, try to uninstall the update and see if it solves the problem. Do not, I repeat, do not try to install IE10 again, because it will silently install the update again, and the video problem will come back.
