SLI mode wrecks media player and media center using vista 64

I'm using the latest nvidia drivers and tried installing the two microsoft
hotfixes, 940105 and 936710 but was informed the fixes "do no apply to your
system". That was confusing since my system qualifies and both fixes do not
appear in my update history list. So my reason for posting is to find a
solution as to why media player and media center display stuttering video or
a black screen when SLI is enabled. When SLI is disabled both applications
perform normally. My two video cards appear in device manage as enabled.
Does anyone know of a link or a fix that can help me? I'm at my wits end
here.

are you running Vista 64bit?

First try resetting your BIOS to the defaults. Some come over clocked or you
may have done so.

Try this cumulative update, make sure you choose the correct version. If you
really have the 64 bit version of Vista -- that is what you want, not the
x86 version. Your error message indicates that the wrong version was
selected:

I searched through my update history and noticed I've installed update
938194. I forgot to mention in my first post that I've tried single gpu mode
(which is what happens when I disable SLI) while using SLI thinking I could
"trick" media player and media center into running normally. No such luck.
The audio continues fine but the video "stutters" unless I disable SLI
globally. I'm thinking the hotfixes might help.
