Heh, that was well hidden ... almost didnt catch that.

I never said it was better than PSNR did I? I think I just said it was my
favourite :) His structural distortion measure for video does outperform PSNR in
VQEG testing though (it's combined with a seperate blocking measurement and also
takes into account the chromatic components). I could make a C implementation of
the image based one if you want.

BTW, how many more bits does a MB with a (0,0) relative MV with skipped
coefficients take compared to an entirely skipped MB?
