Currently I just have TVStandard set to "HD1080i" and Modes set to 
"1920x1080".  I'm letting the Nvidia driver handle the refresh.  I 
assume the refresh rate is dictated by the HD1080i specification.  To be 
clear mine is a rear-projection TV driven by component inputs.

The one problem I do have is underscan.  To get the UI to fit 
appropriatly on the screen I have to set the UI to 1688x988.  I also 
need to offset the screen (I currently can't do this because I'm running 
ratpoison).  Hopefully this week I'll get a chance (have to kick the 
wife off the TV... not always a good idea) to try a different window 
manager that allows me to set the offsets better.

This is my first MythTV setup and really my first serious attempts at 
outputting to a TV.  I have not tweaked with Nvidia's overscan settings 
yet which may also help, although for this setup the nvidia-settings 
console does not allow me to tweak overscan.
