[mythtv-users] Just let my TV de-interlace

1 frame every 30 seconds would match up almost perfectly in the
difference between 60 and 59.94 (the actual frequency of most
broadcast video)  I added a --logverbose 20 when I started X and it
dumped the EDID contents from the TV which gives you which modelines
are available from the TV.  You can either use this to generate a
modeline, or in my case, the metamode was 1920x1080_60 for true 60Hz
and 1920x1080_60_0 for the 59.94 Mhz version.  Xorg.0.log reports the
EDID resolution as a CEA-861B Timing.  There is also one for 720p and
480p

Try setting your default res in xorg.conf to 1920x1080_60_0 instead of
the nvidia-auto-select
That modeline (1080p at 59.94Mhz) for my TV is 148.35 1920 2008 2052 2200
1080 1084 1089 1125 +HSync +VSync

59.94 fps * 30 seconds = 1798 frames

60 fps * 30 seconds = 1800 frames.

Curious to know if that fixes your problem.
