Quote - When I run across that "chest2" node I change it to "Abdomen" and it works out fine but I must admit I don't know it it is actually doing anything with bends because I never thought to look. 

By all means post the script, I have done hours of thinking up splits between parts, this would be great.

The bvh parser is designed to ignore the data that doesn't fit into the bone heirarchy system it's imported into. You can't have two abdomens in a Poser rig, so the one closest to the hip is used, and the second is ignored (it doesn't just go by body part name; it goes by location and association in the IK chain as well)
