Well, I'm glad you made it to the end. The only upgrade that could be recommended is a TV with a superior implementation of 24hz playback. I have some judder as well but I don't find it that annoying.

In the movie theatres, the projector has a shutter that opens and closes at high speeds, which creates the illusion that the video is moving at a framerate close to 48hz than 24hz. On a fixed display like a television, there is no shutter.

I'm thinking of putting my GTX 970 into my HTPC, it'd be overkill for sure but doubling the refresh rate and upscaling to 4k is worth a try with that kind of GPU power.

i'm not sure if my i3-4360 would be enough (dual core 3.7GHz Haswell).

24P playback is annoying, in the end i wasn't able to fix it fully but it's kinda okay.

This would be worthwhile if your display is 2160p. madVR's NNEDI3 Luma Doubling and Luma Quadrupling is known to produce impressive results when doing this type of scaling. Image doubling to 4K requires a very powerful GPU.

I'm gonna give it a try. Regarding 24P, is it possible the TV refreshes too slow to catch up with V-Sync? When 3D mode is engaged my TV disables some color accuracy which i can't get back, but this might be the reason it plays smooth on stereoscopic player?

3D mode engaged -> You can only choose "film" or "standard" mode on my TV settings.
3:3:2 Pulldown has massive motion blur and is unwatchable with "Natural" mode on, i've been really blind.

I basically put my TV settings on "Natural" mode to get the best color/settings possible, but it also enhances input lag and makes artifacts more visible, i'm not sure why this setting is available if this is the root of all evil, gonna test tomorrow.

So far i've found 0 evidence it's the players fault, tried on both DSPlayer/MPC-HC, haven't tried PowerDVD.
