brad - is this using the opensource nv driver or the nvidia binary?
have you seen the quality of a g400 running directfb (and mplayer -vo
dfbmga) to compare?
What model is the card - just curious as the nvidia ones have a wide
range of tv-out chips - some are far better quality than others.
Why are you starting up in 800x600 - it should resize - it does for my
g400.
Are you able to adjust overscan - or is it being displayed perfectly (no
borders etc)..
