Yeah, I've already verified that v4l is working, and that the nvidia
driver isn't complaining about any of my options (UseEvents, NoLogo).

The only thing is for me to downgrade my driver software. The problem
is that while it may be instructive, it might not help me. I've had to
upgrade to a more recent driver to get a real 720p modeline working on
my TV.

Thanks for the suggestions, and I'll let you know what I find.
