Would you mind sending me the line from your .nvidia-settings-rc file
for sharpness? Mine has TVFlickerFilter, TVSaturation, etc, but nothing
for sharpness.

I decided to look into the alignment problem. In a long afternoon
of divide and conquer, I found a magic overscan value that put a
480 pixel image in 480 scan lines for the 4xxx driver. Of course,
the overscan changed with the 6xxx drivers and are now controlled
by the "nvidia-settings" tool. If the overscan value is set to 250
(actually anywhere from 243-250) it is pretty darn close if not
exactly 480 pixels on 480 scan lines. This means that by not scaling
and with accurate frame timing, only data from one of the recoded
fields is displayed per field refresh.

Based on your suggestions, I played around with my settings last night
to see if I could improve on the extremely poor s-quality I'm getting
out of the FX5600XT (possibly a Gigibyte card) I put in last week.
Compared to the onboard Nforce2 quality I was getting, it sucked! So,
beware, I believe that it varies from manufacturer to manufacturer.
and was really happy with the results, so I wanted to respond, so
maybe more people would see your advice.
I'm not sure I could tell much difference by setting the overscan to
250. It was just very slight on my card/tv. But, setting this made
me adjust my GUI size IN MYTH SETTINGS/APPEARANCE down to ~540x750
and set the offsets to X = 15 Y = 20 so that everything stayed on the
screen. Not a big deal.
In "nvidia-settings", set the flicker filter to 1, and sharpness to
about 6 to 8. Set "TV Saturation" to about 172 to 178. The last
one is important. I've found that both nVidia and ATI tvout tend
to bleed bright reds when the TV is set the same as for a TV signal.
The best solution I've found is to turn down the color on the TV set
to just below the point where reds pulsate, glow or bleed then turn
up this nvidia saturation control. Recording with higher sat would
distort the colors in the recording and the Xv saturation seems to
cause distortion also. However, the nvidia setting gives colors more
body without distortion until you are at a point where the colors are
cleanly overdriven.

Now the Flicker and Sharpness adjustment made a BIG difference. I'm
now convinced that lowering these settings is an absolute must.
Scrolling text used to be fuzzy, but now is crisp -- almost too much
with a harsh edge. The Flicker Filter made the biggest difference. I
get a bit of flicker in the horizontal lines in the GUI, but that is
expected on an interlaced TV. To control this somewhat, I have my
Flicker Filter set to ~12.
Turning up the Saturation helped a little to improve the vibrancy, but
this card isn't a good judge of color. I have a new MSI FX5200 coming
today from newegg; will play more this weekend.
Thanks for the (as always) very good suggestions,
