How to I prevent character from wiggling when recording

For the feet, I generally use a single stick labeled with the fixed property. As far as the rest of the figure goes, a good place to start is to look at your handles: do you have all of the handles labled correctly? Are all of the handles being used? (Tagging the limbs with shoulder, hip, etc. without IK enabled just creates errors that only confuses CH). Be sure to check the head as well - an extra head label in the model can cause no end of errors. If you've done that and the error persists, there are a few other things you can try.
