dxva_sig.txt fix

  1. This dxva_sig.txt fix worked on my pc.
    May be on your pc's will too.
    So give a try.

    first my pc specimens are:
    windows xp pro,
    video card Ge Force 7600 GS,
    nvidia driver v.93.71.

    How I find the fix:

    Some time ago I decided to upgrade my Windows Media Player 9 to
    Windows Media Player 10 and than reverted back to WMP 9 because I didn't like it.

    The problem started when I upgraded my video card to "Ge Force 7600 GS"
    and getting the nvidia driver "v.93.71.",
    the dxva_sig.txt started to appear on my desktop
    Being bother with the dxva_sig.tex file continuously appearing on my desktop
    "besides some related issues with, my wmp when playing movies"
    I tried so many fixes which none worked.

    A suggested solution was when I got dxva_sig.txt removal hack from this side,>>>
    which of course didn't work but, gave me an hint on my dxva_sig problem.
    In short the problem was after upgrading wmp 9 to wmp 10 and afterward reverting back to wpm 9, wmp 10 left some files and registries entry which, in return gave me problems when playing some video movies.

    Because i didn't know how to remove completely these leftovers from wmp 10 and afraid to mess up even wmp 9
    and lose all my savings,i decided this other way.
    May be a bit more complicated, but untill someone will not find a better way!!!
    Good luck with this fix .


    Below it's the fix in two steps, the easiest way possible.


    dxva sig .txt >>>fix

    Step 1

    Look in windows root for all the wmvdmod.dll versions.
    Should be there like three versions, on my windows root there were three versions :

    C:\WINDOWS\LastGood\System32 >>> version >
    C:\WINDOWS\RegisteredPackages\{A47B3654-48EE-48A5-B629-97D70175E58F}>>> version >
    C:\WINDOWS\RegisteredPackages\{A47B3654-48EE-48A5-B629-97D70175E58F}$BACKUP$\System>>> version >
    C:\WINDOWS\ServicePackFiles\i386>>> version >
    C:\WINDOWS\system32>>> version>
    C:\WINDOWS\system32\dllcache>>> version>

    Copy wmvdmod.dll version> in to the C:\WINDOWS\system32 and
    C:\WINDOWS\system32\dllcache replacing the wmvdmod.dll's version>

    The step 2 is required, because once this entries from regedit get deleted wmp will ask to
    reinstall the WM9Codecs and the problem starts all over again with the dxva_sig.txt file.
    That means the wmvdmod.dll v. get reinstalled in the C:\WINDOWS\system32 .


    Step 2

    P.S. May be the dxva_sig.txt appering on the desktop it's due to different
    issues than the one i described here.
    May be in a way or the other they are all related to this same issue.
    I really don't know because, I don't know yours pc specs and what
    the cause of the dxva_sig.txt appearing on so many desktops.
