There has been some discussion in other threads about TVs that automatically choose overscan/1:1 or rgb-full/rgb-limited depending on the input signal, maybe this related to your problem?

Hmm, that's a possibility.  I currently have my input named MythTV on 
the receiver, I could try naming it back to PC when I get home.

That being the case, how hard would it be to just tell MythTV to center 
itself inside the display area with a smaller working area?  I tried the 
'Screen Setup Wizard', which resized the screen but left it hugging the 
top left corner so things were overscanned with a ton of blank space on 
the bottom and right.
