There are some strange things :
* foreman is 30 fps, not 15
* the black square helps codecs with a logo, and the bigger the logo, the bigger the help (!)
* there's no way for divx's psnr curve to be higher than ateme's, even at high bitrates, and certainly not on foreman ( and since you give per frame psnr for high bitrate on foreman, you can check that something is wrong ).
