Hmm, not sure I understand what you're saying. I'm not getting pulldown judder, I'm getting a severely messed up picture. Frames will flicker or motion will be incredibly choppy, like it's running at 5 fps at times (although it's not, it just looks that way). The framerate will hop from 23.98 to 48+, other videos it will just play at a consistent 30-35 fps. I use DXVA2 deinterlacing in XBMC (vector adaptive) but it does not properly detect the film cadence and play smoothly. The only way to get it to work (and it works flawlessly) is to use MadVR with film mode forced. I don't want to have to use MPC-HC only for 1080i videos though, if avoidable.
