"Display Driver" ISSUE w/Hardware Acceleration Change(s)

In VISTA HOME SP2, I have always been able to play videos from my camera on this PC - ALL OF A SUDDEN NOW, I cannot, getting this message:

"This video can't be displayed because your video card "MAY" not support the required level of hardware acceleration, or because hardware acceleration is not available".

When I attempt to check it, I get (screenshot)...?

Can any advise, please?

 

Ensure you're running the nVidia driver, not the MSFT driver for nVidia.

 

Thanks - that appears to me to be correct (screenshot), yes please?

 

This appears to be the latest driver.

What recent windows Updates have you installed?

Any other recent software changes?

 

Thanks - I'm updating the driver as I type, and the WIN. Update History is attached...not sure if I should "lose" (uninstall) the "Recommended" Updates or not...?

 

Well, it's very difficult to know what's at the root of this, losing the rec. updates may be in order to test the outcome?

 

Right. I suppose I'll take it a step at a time - updated NVIDIA Driver installing now...

 

Without removing/uninstalling any Windows Updates, things are working again - so it must have been (?:confused?) the NVIDIA Update...thank you very much (and NVIDIA is now set to "auto-update").

Thanks again,
Glenn..
PS ~ Also (and I have :confused NO CLUE :confused if this had anything to do with my problem or not, but), I happened to notice that the PageFile was "out of WHACK" (highly technical terminology there!) - in Windows "Auto-manage", it was "being managed" at less than what was "Recommended" by Windows (so...I don't know how THAT happens, but it was the case) ... in fact, there was about a 1000MB difference...

 

The recommended pagefile size is often larger than the actual, one of the reasons why I always fix the size of it manually.

My guess is that it was a recent Windows Update that caused the bug with the previously working version of the nVidia drivers, I've been seeing a lot of similar cases in the last month or so. Anyway, you're up and running now - I'd not update anything (outside of updates for security reasons) while it still works 100% - if it ain't broke ...
