Using Puppeteer will create a key frame on every part of the figure,. unlike manually posing to create a key frame, which will only create keys for the parts of the figure which are moved.
this means that you need to delete all the keys for the figure at that frame, to restore the tweeners back to the default DS tweener.
Hope it helps
Daz Carrara has a Full set of animation features and controls, full key-frame editing, multiple tweener types, and a graph editor,.
