I'm working in CS5, on a Mac Pro quad core tower.
I have a screen where someone's thumb is obscuring one of the corners and I need to insert a graphic onto that screen. So far I've managed to track the screen successfully but I cannot get the Mocha Shape to translate correctly in after effects. When I paste the information back into AE it distorts the screen insert.
These were my steps to create the mocha shape
1. create a spline in mocha and track, setting the surface points as if I had 4 true points instead of three and a thumb.
2. create a nicer spline that goes around the thumb and linked that to the tracking data from the first spline
3. copy the shape data to AE, I chose to copy it to the image that was going to be inserted over the screen
The end result is that the image I'm trying to mask is tiny and its floating around in the mask rather than filling it.

You should Paste Mocha's Shape Data onto the footage that you tracked. Your final composite will involve at least three layers; from top to bottom -
1) Original footage with Mocha Shape Data applied
2) Insert Layer with CornerPin Data applied
3) Original footage
Layer 1 above will mask the thumb so that it is over the insert layer. Perhaps you will want to solo each layer so that you have a better idea what each layer entails.
Lastly, the reason for the visual anomaly is that the size of your insert is smaller compared to the tracked footage.
