Is the shot being placed on the screen a full screen shot.
By that I mean, if your comp & tracking shot is 1920 x 1080, is the video being place on the screen the same size. I bet its not.
If this is the problem, take the footage and precomp it in a size that matches your main project.. Then stretch it to fill the full screen.Then apply the tracking data to the precomp.
I believe in MI+ there is a choice that does this for you automatically.
