Well, if by "TV that you are trying to play" you mean the content
playback, you can actually separate the size of the UI from the playback
size in the Playback setup menu.  That I do to maintain the correct
overscanning of the content playback regardless of what myth is doing
with the UI.

Indeed.  Exactly my point too.  But I'm only complaining about the UI
due to the ability to decouple the playback size from the UI size per
the above.

Right.  But rather than just doing "full overscan" so that what you see
being played back on your nvidia card exactly matches what you'd see
with live TV, you are trying to find some "happy medium" where happy
medium is not being equal to "as if you were watching on TV".

I am on the 96 drivers, but I still get that overscan that
nvidia-settings can do.

Well, I have the overscan in the nvidia settings set perfectly, so that
playback looks exactly like it would direct from cable to my TV.

It's getting the UI to fit inside the visible area *without* reducing
the size of the UI canvas that is the problem here.


Sorry Brian I am not getting this.  If you adjust overscan correctly using NVIDIA settings for the Desktop UI, then mythtv should 
just scale / work using default settings.  If you are using a non standard UI setting, I'd set the UI right first, and then 
re-adjust mythtv to the size you want.  The other way around I'd expect to give grief.
