Is it possible it could be the modeline causing the problem? Have you
tried running the NVidia TV-Out config tool or setting up your
xorg.conf file with a specific modeline? I'm using a basic ATI 9100
Radeon on-board chip and S-Video connection, and the video quality is
very good. I'm sure you should be able to improve your TV-Out
experience!
