Well I looked at a gspot of all the clips and I noticed that the TMPG one has the S170 video icon lit, which does something to the video RBG-> YCbCr, even though nothing like this was picked in the options, and like I said I used the same avisynth script for all three encoders. Anyway heres some samples, taken from the beginging for fast paced scenes and colors, theyre about 85-90 sec samples, no audio sry, didnt see the need

I also looked this up on doom
Color Coefficients and equivalencies:
http://avisynth.org.ru/docs/english/...olormatrix.htm (Colormatrix 1.9 manual) says:
BT.601 = BT.470-2 = SMPTE 170M (BT.601 is an update of BT.470-2)
BT.709
FCC (similar to BT.601, can be handled on its own by Colormatrix v2.3)
SMPTE 240M (similar to BT.709, can be handled on its own by Colormatrix v2.3)

Is it the case that 170M is the same as 601/470, the screens are completely different, i think somewhere the colormetry is getting screwed, I can post my script if necessary
