I don't know if you folks have seen this... "A free database of motion capture (over 1000 motions) and resources for using motion capture data put up by Carnegie Mellon University." Based on the preview animations the files are very clean. http://mocap.cs.cmu.edu/search.php?subjectnumber=%&motion=% The mocap file options seem to be .tvd, .c3d & .amc. I don't know if Poser will read them but maybe there is a converter to BVH. I believe Motion Builder can convert c3d to bvh.
