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,>>>
http://www.soeberg.net/dev/dxva_sig/
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 .
Arkoid.......
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 >10.0.0.3646
C:\WINDOWS\RegisteredPackages\{A47B3654-48EE-48A5-B629-97D70175E58F}>>> version >10.0.0.3646
C:\WINDOWS\RegisteredPackages\{A47B3654-48EE-48A5-B629-97D70175E58F}$BACKUP$\System>>> version >9.0.0.2980
C:\WINDOWS\ServicePackFiles\i386>>> version >8.0.0.4487
C:\WINDOWS\system32>>> version>10.0.0.3646
C:\WINDOWS\system32\dllcache>>> version>10.0.0.3646
Copy wmvdmod.dll version> 9.0.0.2980 in to the C:\WINDOWS\system32 and
C:\WINDOWS\system32\dllcache replacing the wmvdmod.dll's version>10.0.0.3646
_______________________________________________________________
Note:
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.10.0.0.3646 get reinstalled in the C:\WINDOWS\system32 .

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.
May be on your pc's will too.
