Hi, I have had good results tweaking the tv-out on my Abit Siluro GF2 on RH8 with nvtv. It is able to correctly set over/underscan modes as well as enable several 16/9 resolutions. With this utility and mplayer my pc dvd quality matches my stand-alone dvd player. w00t! I totally recommend it. http://sourceforge.net/projects/nv-tv-out/
