Sure they can. There are sites that maintain archives. You can get the ones you want here:

Guru3D is reliable.
As to your problem, I don't see anything wrong in the MadVR data. I don't suppose you have the ability to hook up the other TV, just to eliminate the TV as the problem? Maybe take the computer to the TV? I doubt very much that that's the issue, but just to be safe...
Personally, I would backup the PC with Macrium (as I think I mentioned to you before Shoe), wipe the drivers and install the 445.75 that you like, and see what happens. If no joy, you can always revert to the snapshot and nothing ever happened.

Check monitor refresh rate set in your Windows settings as I mention earlier (its a new option in 2004) .. its possible it is set at 60Hz, which makes switching to 23fps not possible
EDIT: well ... as i understand it, GPU will switch to 23fps, but Windows will maintain 60Hz on display which will result in stuttering as 60 is not nice multiple of 23.976
wer:
If your TV won't show you the refresh rate (I don't think mine does) then if you pass the signal through a receiver, the info screen on the receiver should show you the refresh rate and resolution of the video input signal.
tij:
This control of refresh rate in Windows (not in GPU settings) is new. Suppose to fix flickering/stuttering on multi monitor setup
aka if monitor is 144Hz and TV is 120Hz - in the past this will result in stuttering/flickering ... the idea now is you can control/force display refresh rates ... to eliminate flickering you set rates as multiples (in 144 vs 120 ... you set one as 144 the other as 72 ... or one as 60 the other as 120) ... this eliminates flickering across multiple displays ... but can introduce other problems (typical of Microsoft)
In The Shoe example ... Windows might have been conservative and set refresh rate on his OLED to 60Hz (which will play 60fps movies nice, but will have problems with 23fps content) ... setting refresh to 120Hz should eliminate that problem
This is pure guessing ... as I am not on 2004 (I am not early adopter as new Windows updates tend to break stuff) ... but The Shoe problem really sounds like problem with refresh rate that Window pick for him as default.
TheShoe:
today i am going to connect the new htpc to the other tv to eliminate that. directly, so i remove the processor (marantz) out of the chain.
will also look at the windows refresh rate serting, though both are on windows 2004 and one works fine while the other does not, so not sure about that.
re: the backup - just downloaded the free version yesterday. planning to use that goong forward if it works well. thanks for that recommendation! will also check guru3D - forgot about them. nVidia for some reason omits that driver version from their list of older versions one can download.
more later...
