Just a heads up, 

Dark Shikari is hosting a blind codec comparison and schrodinger 1.0.9 is represented. The thread is here: http://forum.doom9.org/showthread.php?t=154430

So far Dirac is faring quite poorly (see the samples near the end of http://x264dev.multimedia.cx/?p=377). Are there any non-default options that should be applied. All I know is that he used constant quality.
