Are you sure that you are running with the nvidia binary driver? I once
had some trouble getting a Ubuntu install to switch from nv to nvidia.
You can send the X log directly to me if you want. If you are running
the nvidia binary try another tv app like tvtime or xawtv. Also try
playing some video files with mplayer or xine.
