When I have an itunes video playing in the background and I go to access Mission Control, its very jerky and stuttery and not at all smooth, when I disable the video, the problem goes away.

Just a hardware issue. That's typical of trying to move things around on screen while video is playing. Your GPU/CPU just isn't powerful enough to render all of it together smoothly.
