Help exporting BVH files from Poser

Sonofbelmont

Hi
I have created a very simple animation in Poser 9 (demo version) using Genesis and then exported it as a BVH file but the animation does not import into Daz studio correctly or back into poser correctly either it looks like the influence of the IK goals along with any hip movement are being left behind on export. I was just wondering if anyone might know what I'm doing doing wrong to be getting these kind of results?

any help would be greatly appreciated
thanks
