oh ok thanks for the clarification Didée...well everyone calls it "chroma upsampling bug" :

it basically makes the red blocky to hell...and I'm not watching HD to get blocky reds
so is there a way to overcome this issue in AVS ?
I think I read that when you checked "HQ" in ffdshow, it was using some YV12>YUY2 conversion script(from Avisynth actually).....I read it in the ffdshow thread :

anyhow ConvertToRGB32 can't be multithreaded, so this can't be used in realtime in ffdshow
