Watching 24p movies with judder is terrible and I don't think any video purists would suggest that. You do not need motion interpolation to avoid judder
I also tested all the processing options of my TV and turned them off because they damage the image, most obviously by converting to 4:2:2 to do the processing.
I agree that one should test themselves but the processing on many TVs does do a lot of damage to the output from madVR.
