Once upon a time, I was trying NPVR on a old, low power system, and had it working pretty well on Win7 using the MS DTV-DVD video decoder and AC3 filter. Then I tried ffmpeg and had choppy video. I went back to the MS decoder and now had choppy video with that. Even with ffmpeg uninstalled, I had the choppy video. The only solution was to reinstall Win7; the MS decoder then gave smooth video. And has, ever since.
So, I think you have so much stuff on your system from trying so many decoders, etc., that it is completely messed up. I recommend a new install of Windows 7, then NPVR, then AC3 filter for audio. Set up NPVR with video renderer as EVR, audio renderer as default, MPEG2 decoder as MS DTV-DVD decoder, MPEG1 decoder as AC3 filter, AC3 decoder as AC3 filter, and everything else as disabled. Do not install anything else. Do not use Windows 8.
Scan and setup the channels, and see if that works.
If you are using an HDPVR or Colossus for a tuner, ignore the above. The devices create h.264 video. I don't think an Atom has enough power to decoder h.264. It is more compressed than MPEG2 and requires more CPU or GPU to decode.
