If you can send me the AVS script, I'll do tests with it and post results here.

Which AVS script? Are you looking for the crop values I used on my capture of the BBC Test Card G? If so, I found this on my hard drive:

MPEG2Source("D:\Video projects\comb filter test\dr198 s-vid2.d2v", cpu=0, upConv=1, iCC=false)
temporalsoften(2,255,255)
#Crop(114, 146, -580, -398) # 50% grey
#Crop(252, 436, -250, -108) # video black
#Crop(338, 142, -364, -398) # 75% grey
#Crop(268, 100, -250, -442) # video white
#Crop(208, 186, -442, -314) # cyan (75%)
#Crop(444, 184, -212, -316) # red (75%)
pointresize(720,576)
coloryuv(analyze=true)

You will need to remove the leading "#" for each line and note down the stats for each colour in turn, and you  may need to adjust the crop values if your capture is positioned differently to mine.
