Hi gordon13, your question sent me scrambling because I always use the middle dantien. You are right the video does show the active exercises using the lower dantien.
When I went to the manual (page 8) you'll see that you can draw the energy into either the middle or lower. As soon as I read this I could hear the words from the audio lessons saying the same thing. So it comes down to your choice.
I prefer the middle dantien myself... as a result of my own experience prior to entering SFQ, I have a middle dantien bias.

You are perfection.
