Check your display settings for the TV Out (especially vertical/ 
horizontal refresh and resolution) on your windows laptop, and try to  
mirror them in your xorg.conf

nvidia tv-out is generally speaking about as good as it gets for cheap 
(ish) consumer cards, so i doubt the card is at fault, it'll be your  
settings :)
