Interesting reading on this thread - I started to have similar problems on my setup with a gt430. Everything was great months ago - I believe I was on the old danellia hd audio build and one day I got update happy and updated to the latest geforce driver and the latest nightly. The combination of all that caused my playback to suffer - it was like there was tearing in the lower 3/3 of the screen - when motion would pan up and down it was like the bottom 1/3 didnt want to pan - it looked jagged and out of whack. In addition, the frames were jacked up around 40 or so for most movies. I then tried rolling drivers back and re installing what I thought was the right version - none if it worked. I tried some of the new video playback options, but they looked different and didnt work.
So then I found someone else was having similar troubles and followed the advice here and thanks to greeneyez relinking the original hd patched audio by danellia, things are good once again. Running 11.0-HD-Audio Git:20120417-2f965ac
My settings are currently DXVA Render method / Use DXVA2 / Adjust display to match video - yes / Pause during refresh rate change - no / Sync playback to display - yes / AV sync method - video clock.
The key for me was to sync playback to display. Once I did that, all was well. When I tried that on the nightly version - didnt work. Only downside I have right now is some movies dont play the right playlist - so I have to reauthor them. for example, iron man 2 plays the version that overlays the SHIELD info.
Other than that all is well again. Hopefully future nightlies / stable releases will play the video as butter smooth as the one I have installed now.

Things I tried last night -
Disabling DXVA2 - no effect
Disabling Vertical Blank Sync - no effect
Setting desktop to 1080p24 and syncing xbmc to display - no effect
Plugging hdmi directly into projector, bypassing Onkyo receiver - no effect
Running xbmc in windowed mode/true fullscreen mode - no effect
Since MPC-HC runs just fine at 24p, I hope I can get XBMC to as well. Things I have yet to try -
Try all of the above using the Intel 2000 graphics instead of the Nvidia 430 which I have been using
Uninstall XBMC Eden 11 HD audio patch, install XBMC 12 Frodo nightly, try again
Right click XBMC.exe, go into compatibility mode, check "Disable Desktop Composition"
If none of that works I'll uninstall XBMC and try Plex. Since Plex is based on XBMC I don't hold out much hope for that working either. If I can't get any of that working I'll buy a popcorn hour or something similar.

Here is the latest (and last one) that the developer who made the HD audio patch released : https://github.com/downloads/DanielaE/xbmc/XBMCSetup-11.0%2BHD-audio-20120417-2f965ac-dx.exe
. It`s 2 months newer than what you are using, and it`s what i`m also using. Try that before you venture into nightly builds.
Also, try resetting the XBMC settings to default settings (go in to C:\Users\Workstation\AppData\Roaming\XBMC\userdata and delete "guisettings.xml"), this will reset XBMC to the default settings (you won`t lose you libraries, don`t worry about that)
Now, start it up, go to Settings -> Videos -> Enable DXVA and Adjust refresh rate to match video
Then to System -> Audio > Select HDMI , Select the settings for DTS / DTS-HD / True HD / AC3 bitstreaming and select the passthrough device as "WASAPI - Nvidia HDMI audio" or something like that.
Using only these settings, try playing back some movies and see how it behaves.
PS : "Worstation" is actually your Windows user name.
