I'm also looking for help with a FX5200 video card and can contribute
a few facts - not that it will help much.
Shifting of the picture occurs only on HDTV channels, and the right
20% of the picture is off the screen. When this shifted picture is
compared with a picture from a real HDTV set, the shifted one has 10%
more of the LEFT side of the picture!
Another comparison I can describe is between the FX5200 and either of
two newer cards, an N6200GE and an N6600GT. All three of these cards
are fed to the same (ten-year-old) TV set, but only the FX5200 has the
shift. Both of the newer cards play SDTV and HDTV quite well. It's
easy to tell if there is a shift because one of the local stations
broadcasts everything in HDTV, adding left and right "advertising"
boarders when the program originates in SDTV.
The nvidia driver is 8762 on the FX5200 and the N6600GT. All three
systems have PVR-250, HD-5000, and HD-3000 cards.
It's discouraging to read that experimenting with various Modelines
doesn't have much effect. I spent much of today searching and reading
about Modelines without finding enough information to even construct a
Modeline. So, the message is clear: Start fresh. Tomorrow morning.
