I made some of the changes that were mentioned in this thread:
http://www.gossamer-threads.com/lists/mythtv/users/131462

When I check my xorg log there is an entry like:
(II) NVIDIA(0): Not using mode "ATSC-480-60p" (no mode of this name)


Look further up in the logfile. It should say something like "Not using modeline "ATSC-480-60p": blahblah".... Could be frequencies (although the monitor ones look fine), dotclock, no interlace, or the weird nvidia-specific restrictions on integer divisions by 8's in the syncs. If the last issue, the logfile is specific about the problem.


If you want a D1 480i resolution (same 480i frequencies, DVD-friendly number of dots), search the archive for 'coryntsci'. It's the modeline I use with my modulator doohickey.

Not sure why it says there isn't a mode.
