[mythtvnz] Nvidia TV out overscan

[Hadley Rich]

Hello list,

I found some time to play with my setup this afternoon and discovered 
something that may be useful for the list archives.

I have a Nvidia FX5600 using S-Video out to a 32" widescreen CRT and up until 
today had a little underscan in X.

I'd briefly played with the TVOverScan option in xorg.conf when I set the box 
up but couldn't get enough overscan to completely satisfy me.

Today I was playing in the nvidia-settings utility and discovered that the 
overscan slider there allows for more adjustmen than the xorg.conf setting.

I now call `nvidia-config --load-config-only` in my xinitrc which sorts the 
problem very nicely.

Hopefully this helps someone sometime. Now the only thing left for me to 
investigate is the dreaded prebuffering pause issue, but that's not bad and 
can wait a little longer.

As an aside, I had the chance to setup a Myth box on a 50" HD plasma the other 
day, it went quite well and looks very nice.
