I modified the default script to only use drop to floor for the first frame, recording the change in the Hip's YTrans. For the rest of the frames I adjust the hips YTran by this amount. With this method I can maintain a figure jumping off the ground. The other method drops the figure destroying the jump. I have tested it on a few BVH files with jumping in them and it appears to work pretty good.
