Thank you tccstudent for the media player advice, I was unable to get it working with quicktime. As far as the video goes, it doesn't seem to me like you are using any of the principles of taijiquan. For that matter, it doesn't look like you're using much boxing either. Your footwork is sapping all the power from your strikes and you seem to be unable to root yourself to generate strength in close proximity. I hope this wasn't supposed to be a demonstration of taijiquan because it seems a bit like amateur mma.
