instead of having a chain reaction of events that lets the power flow from your lower body in to your arm you have a very mechanical jerky type motion.
your hip rotation and shoulder rotation are happening all at once, your hips should lead your shoulders and help pull them around. you're also taking huge fan swings with the disc like you're hitting a baseball. the disc shouldn't move in a circular path, it should go back and then come straight through your right pec.
to get rid of the squatting do a lot of throws standing still, up on your tip toes, without an x-step. after you do that for a while try walking through it all very slowly until you get the feel for it.
remember that the explosion comes when the disc gets to your right pec, before that it's all a steady and very smooth acceleration that gets you in position for the hit. right now you're just trying to throw it really hard and accelerating way to soon to get the full power of your body in to your throw.
one last tip and i'll shut up, you seem a bit antsy before you throw. maybe it's because you're taping but i'd suggest taking some deep breaths and slowing down your breathing before throwing. remember, smooth is far.
