dxva_sig.txt Microsoft's fix applies to Windows Media Player 10. I still have AGP and Media Player 9. Whenever I play a Windows media video, a dxva_sig.txt is placed anywhere on the hd and the desktop too. I don't like Media Player 10 very much. One cannot uninstall it and restore Media Player 9. I wonder if it's the same with Media Player 11. I don't want to install it since I had to format the hd and reinstall XP last time. I checked my drivers and it seems to be wrong here :/ wmp.dll - v.22.214.171.12449 wmvcore.dll - v.10.0.0.3802 Wmvdmod.dll - v. 10.0.0.3802 Note that I have Windows Media Player 9.
