Somehow my DirectShow got screwed up, and I can't figure out anyway to fix it short of a Windows re-install, which I of course want to avoid. I'm looking for suggestions.
Here's my situation:
Playback suddenly went from super-smooth to severe stuttering every 2-3 seconds when playing HD content, and no aspect-ratio controls and 4x3 SD content stretched to fill my 16x10 screen.
When I looked at my Video Decoder properties in Config, with my configured NVidia Decoder, the Video Format and Decoder Format boxes are strangely blank. Normally the Decoder Format shows the DirectX video acceleration mode that will be used. I've attached a screenshot below.
While the NVidia Decoder is the one that shows these blank spots, playback severely stutters regardless of the decoder I chose. One of the decoders won't even open it's Video Properties.
When I try to open a video file in GraphEdt, I get an error: Some of the streams in the this movie are in an unsupported format. Then the graph that it shows me doesn't connect the Video pin from the MPEG2 Demuxer to anything. Screenshots attached, showing a .ts file, but I get the same result with an MPG.
Here's what I've tried to fix it. Inspecting the system, everything else appears to be ok from what I can tell. Dxdiag says everything's working fine with DirectX. No errors anywhere except for a niggling unknown device in Device Manager. I can't figure out what it is, as all the system hardware seems to be accounted for. Maybe it's been there all along.
The first thing I tried was reinstalling the NVidia Pure Video decoders. Went fine but no change. Next, I reinstalled all my video card drivers - again fine, but no dice. Third, I downloaded dxsetup from Microsoft's site and ran it, installed fine, but still it's screwed up.
Oh, I did fine one strange thing going on in my Event Log. The first time the error appears is within a minute or two of installing 99.12. I honestly don't know if gb-pvr's installation has anything to do with these problems, but it does seem suspicious. Unfortunately the first error doesn't give me enough info to have a clue what to do, and I wonder if it's related to the unknown device error I have. The Windows Media Network Sharing Service it complains about I've since disabled - I didn't want it anyway. Again, I've attached some screenshots. If these are just a red herring, I apologize. I'm just trying to be thorough in case someone recognizes something.
I'm not sure where to go from here. I could uninstall GB-PVR and re-install the older version, but I don't see how that's gonna fix the anything. I really want to avoid a complete wipe and re-install of the OS, but I'm out of ideas. Any suggestions?
