Hello! This is my first post here at TechSpot, appears to be a great forums. Which brings me the point...I have QUITE the DirectX/Codec issue. It began with me noticing any .wmv video file played by all 3 off my media applications had either their colors inverted and wild looking, or simply didn't play at all (in the case of Winamp). Around this same time I noticed "dxva_sig" appearing on my desktop. I didn't think much of it assuming it was just a troublesome form of spyware or the like I had to root out or reformat to deal with. Also, I recently bought Call of Duty 2, and when I select DirectX 9 for it in the Graphics options menu, it will freeze up on the level loading screen...however it curiously runs fine (albeit much worse looking) on DirectX 7. After googling "dxva_sig", I began to tie it all together...obviously theres a problem with some media codec or my installation of DirectX 9. I attempted to run to the .exe provided to fix this problem by Microsoft via the Microsoft site, upon which I get this error: "Setup cannot continue because one or more of the prerequisites required to install KB888656 failed. For more details check the Log File c:\windows\KB888656.log" KB888656.log contained about 27 lines of text which I won't paste onto here unless its requested. ANY help at all would be GREEAATLY appreciated. I do a lot of PC troubleshooting for my friends, and my own home network and 4+ PCs...but this problem has me stuck. Thanks!!
