mini SD downconverted image is not centered

[LISound]

The overscan for the sd output on my mini is giving me an image that is not centered.
if i use letterbox or anamorphic, I'm seeing the more of the image being cut off on the right side of the screen.
When i hit the underscan button on my sd monitor, I get a large black bar on the left. it seems the sd image is being pushed to the right.
I understand over and underscan and this is not that issue.
I'm under mc 6.0.1.1 and 10.7.3 on a dual 2.26ghz mac pro
driver version is the one listed for mc 6. and 10.7.2
I only see this on the SD downconverted image.

Hi,

We are not seeing this issue here, however, we would like some additional details for better troubleshooting the issue in house.

Can you conform your MXO2 driver version? ie 3.0?
What are the Video Output settings set to in MXO2 Preferences? ie Set main channel format to, Channel Selection etc?
What is the model of your SD monitor?
Have you tried using a different SD signal (ie. Composite) or another monitor?

Please let us know your results.
