On all mpeg2 I can have (dvd rips, dvb recordings, fresh HCEnc encodes...),
this script does show something wrong :
Code:
a=mpeg2source("v.d2v") # or avisource("v_uncompressed_by_virtualdub.avi")
b=ffvideosource("v.mkv") # muxing the stream in a mkv does fix the ffms2 frame inaccuracy
subtract(a,b)
histogram("luma") # needed for humans eyes

I remember when testing some ffdshow settings, I did try the "use speedup tricks" and got some funky pixels like that (but much more visible).
Dunno if it is related since both ffms2 and ffdshow use ffmpeg.
