in c6pro, poser manikin.obz file (with ohio Female1_B24_WalkToCrouch.bvh skeleton attached to it) animates as above. maybe phil (or somebody) has got a script that attaches a bvh skeleton to a poser geom file.  or maybe there'll be said function in poser 8.  try the Female1_B24_WalkToCrouch.bvh instead of the Male2_WalkToCrouch.bvh.  they've both got the same bodyparts excepting the tallywhacker AFAIK.
