Thanks, I resorted to using PotPlayer and everything's fine now, thanks!  Definitely MPC-HC issue.

Recently purchased SVP4 and now having it installed with klite mega, noticing that if i have a wmv file and plays it on mplayer classic on SVP, it indicates that it is running at 60fps (original is 30) but i do notice the stuttering.

If i rename the extension of that wmv to mp4, the video does proper smoothing (noticed from my eyes, although it still shows at 60fps)

renaming wmv to avi does not convert to 60fps properly as well.

I only have KLite Mega installed with MPC-HC, and am sure that nothing else was installed that could possibly hinder avisynth+ffdshow.

For all three extension cases, ffdshow does use avisynth with the temporary created AVS script.

Any idea?
