You need avisynth and a bit of knowledge of avisynth scripting.
There's an avisynth dedicated forum on this board, maybe you should start from there.

Get MSU Video Analyser, import your file into it, choose psnr and go. You might need to mux it into avi/mp4/mkv first, I frget whether mainconcept its only raw or not.

For YUV, see the avisynth docs on RawSource. (Maybe Fizik's russian docs would be more understandable?)

yes it is. i dont know about any available uncompressed AVI files. i have uncompressed yuv files though.
Mux means MUltipleX, "inserting" one or more streams into a container (for example MPEG-2 into AVI).
