- jack: don't assign all reviews to tim by default :) ...nd i'm trying to investigate why. tim suggested i look for DC shift, but I don't thin it's a problem. He suggested I do a psnr for each kind of pixel and ...

- d: That's a different thing. I don't think we should make this meeting longer just for that. - jm: I don't know who else tried block size switching with current master, but whoever ...
