Jitter may be the result of the power supply frequency being different from the refresh rate of the video interface. If you have a 50 Hz video signal on a display connected to 60 Hz power you may see a constantly wobbling image. This is my experience from the late 70s when monitors were essentially cheap TV sets without a tuner.

Thanks, Marcus. The 82163 is an "A" so both the refresh rate and power line frequency are 60Hz. I was going to try the TV Out to see if it was jittery, too. Any suggestions would be greatly appreciated.
