I remember reading your article, Aaron.  Maybe I am missing it, but I currently have no problem with over or underscan.  Everything is fine, except with TMT3 (which I neecd to reinstall since the reinstall of Win7).

I submitted a support ticket with Arcsoft.  I have not been able to try this yet, but here is what they recommended:

Please change MCE resolution as the same of your desktop resolution. The following are the steps:
MCE -> task -> Settings -> General -> Windows Media Center Setup -> Configure Your TV or Monitor -> Display, next -> Monitor, next -> Select Your Display Resolution: select a resolution which is same as your desktop resolution
