you're both right. The daily binaries including untested experimental code
are dangerous (for Joe User). I've already written doom9 about this (and
because I liked to know what the problem really was). What is a bit
disappointing for me is that doom9 didn't wrote me at all that he had any
problems with the comparison. We were in contact when he did his last
comparisons and recently we had some (more or less unimportant) talk about
"when will b-frames be ready etc.". I would have advised him to simply used
an older build...

yeah, but we have no real stable version yet. I'd say we should do a lot of
testing and first release when b-frames are ready (and maybe qpel also).
This should improve the current situation a lot.
