I actually saw your video with the vex and decided to wire it up with one of our Cortex's.

The problem was that the gyro reading would constantly decrease like there was some kind of drift even though the robot wouldn't be rotating. I don't know why it was doing that, and I only had a class period (1hr 15m) to work on code and getting everything worked out.

I could work on it some more and try to get it to work, but I'm much more fluent in LabVIEW than robotC so I'd rather try getting an FRC sized prototype working.
Clearly a FRC sized prototype is the direction we are heading as well.

As for your gyro drift. The initialization process may not be completing properly before the robot is moved.
I added the red LED to mine to indicate when the initialization process has finished. This bot is coded in "C" using MPLab as the IDE. It's old school, but the principals are the same.
