[mythtv-users] ION + VDPAU + no composite and still tearing

[Brian J. Murrell]

I've got a Revo 1600 which, as you know, has an ION chipset in it, so
quite VDPAU capable, however I am still experiencing some quite nasty
tearing.  I've made sure composite is disabled in my xorg.conf:

# cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister at builder75)  Thu Apr 22 11:44:23 PDT 2010

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildd at palmer)  Fri Apr  9 10:35:18 UTC 2010

I think I have my .nvidia-settings-rc file set with the correct/needed
options:

RcFileLocale = C
ToolTips = Yes
DisplayStatusBar = Yes
SliderTextEntries = Yes
IncludeDisplayNameInConfigFile = No
ShowQuitDialog = Yes
Timer = PowerMizer_Monitor_(GPU_0),Yes,1000
Timer = Thermal_Monitor_(GPU_0),Yes,1000

Which I apply in my mythtv-frontend startup script with:

su - mythtv -c "export DISPLAY=:0; /usr/bin/nvidia-settings -l -c :0"

Any ideas?

Anyone else with a Revo 1600 that doesn't experience tearing want to
provide their xorg.conf and/or .nvidia-settings-rc file, or commands you
use to set up the nvidia settings?

Cheers,
b.
