I don't know, but so far I was under the impression that for the first pass most advanced parameters are not needed. The passlog file just gives a compression curve to the second pass (i.e. provides info about the compressibility of the source), and the b_sensitivity param in the second pass should not depend on the b_strategy param in the first pass. But maybe I am wrong...
Just saw that my second pass params use "-g 12 -bf 2". Doesn't this override any "b_sensitivity" param?

This is one of the weirder things about these HQ params. The Fox New matrix comes from manono who extracted it from a commercial DVD, and it eats even more bitrate (and provides better details) than the classic Fox Home Theater matrix. And convential wisdom tells that this is a High Bitrate matrix.
When I was working with Fishman on the original XHQ parameters I suggested to use a matrix designed for lower bitrates, but his tests showed that the MPEG Adapted matrix worked better even for very low bitrates. And in the DVDStyler forum a member SilverSolver found that the Fox New matrix gave even better results than the MPEG Adapted matrix. So I made the Fox New matrix the standard for these XHQ params, and so far I found the results very good (and I got no complaints from forum members).
